Description

  The present invention uses an aluminum empty can as an aluminum can for beverages or an aluminum bottle used for beverages in which an aluminum metal material constituting the container is exposed on at least a part of the outer surface of the bottom as an anode structure. The present invention relates to a wet primary battery.

  As an instant emergency battery at sea, there is a seawater battery that uses silver chloride or lead chloride for the positive electrode, magnesium for the negative electrode, and seawater as an electrolyte. At sea, seawater can be easily obtained and used in large quantities when needed, but silver chloride, lead chloride and magnesium are industrial special materials and are not readily available in large quantities in everyday living environments. .

  Aluminum metals and aluminum alloys mainly composed of aluminum are currently produced in large quantities, processed into various daily life and household products, and supplied in large quantities at low cost. Building materials such as doors, window sashes, verandas, fences, horticultural agricultural equipment tools, etc., and for household use, such as pots, basins, tableware, aluminum foil, cooking partition molds, gas range covers or ventilation fan cover frames Such aluminum metal or aluminum alloy products are abundant around us. Therefore, in place of magnesium metal, which is almost difficult to obtain in daily living environments, waste aluminum metal and aluminum alloy products that are readily available at low cost can be instantly used in the event of an earthquake or other emergency. It is desired that the battery can be used as an electrode of a battery.

  Aluminum metal is a metal having a large ionization tendency following magnesium, and has high activity. Batteries using an aluminum metal or an aluminum alloy containing a small amount of magnesium as a negative electrode have been studied for a long time. Batteries using aluminum or aluminum alloy as the negative electrode are expected to be lightweight, high voltage, and high capacity, but control that the high activity aluminum negative electrode reacts with the electrolyte and causes gas leakage and electrolyte leakage As a dry battery, there is a problem that the storage life is short, and it has not spread as much as a manganese dry battery using zinc as a negative electrode. In JP-A-2002-298862, in a primary dry battery using aluminum as a negative electrode, a countermeasure is taken to prevent deterioration due to self-discharge or gas generation by the action of aluminum with the electrolyte, and an initial voltage of 2.03 V, one month. A coin-type sealed primary dry battery having a discharge capacity of 9.4 mA is shown.

  The problem that the negative electrode aluminum interacts with the electrolyte and deteriorates due to self-discharge and gas generation is not a dry battery, but a wet battery that injects an electrolyte when it needs battery action, such as a seawater battery, This can be avoided if the gas generated using a container with gas is diffused into the atmosphere.

  When a battery using aluminum metal as a negative electrode is constructed, another material that reacts with the aluminum metal and is consumed is an electrolytic solution. In scientific experiments, salt water is infiltrated into cooking paper as an electrolyte, wound around Bincho charcoal serving as a positive electrode, and an aluminum foil serving as a negative electrode is wound thereon to constitute a Bincho charcoal-aluminum battery. If the area of the aluminum foil used as the negative electrode of the battery is increased, a current of several hundred mA flows in a short time, but the load voltage is 1 V or less, and the voltage / current is greatly reduced in a few minutes. Therefore, a battery using such a combination of materials has not yet been industrially produced and sold.

In general, various industrial chemicals are required to produce an electrolyte that is more suitable than a saline solution as a battery. For example, in Japanese Unexamined Patent Publication No. 2001-23650, an attempt to use an empty beer can as a negative electrode of a battery is shown. In order to remove a synthetic resin film on a surface, an additive solution of hydrofluoric acid is used as an electrolytic solution. using. However, hydrofluoric acid is a dangerous substance and is not easily available in daily living environments.
JP 2002-298862 A Japanese Patent Laid-Open No. 2001-23650

  A set of batteries made of aluminum metal waste and used in daily life environment as an electrolyte, in the event of a disaster such as an earthquake, in other emergencies and emergencies, higher than 1.5V of manganese dry batteries, red light emitting element We would like to realize an instant wet primary battery that can obtain a current of 10 mA or more at 1.8 V at least several hours.

  When manufacturing a dry battery industrially, various chemicals of acids and alkalis such as sulfuric acid and nitric acid are required as an electrolyte. However, these chemicals are generally not commercially available and are hardly available. Therefore, it is more suitable than saline when combined with aluminum metal from among the daily household products that are in daily living environments, can be used in emergencies and emergencies, and are relatively inexpensive and easily available. We searched for an electrolyte that could be used.

  As a result, it was found that there are a wide variety of electrolyte agents around the current daily living environment. Conductive aqueous solutions such as cooking vinegar, flour, citric acid, fruit juice, various food detergents, bleaching agents, home cleaning / antifungal agents, kitchen / bathroom or toilet deodorizers, disinfectants, There are a large amount of general commodities that are various electrolytes that are liquids, powders, and solids other than beverages such as disinfectants, cleaning agents, other hot spring sources, and fertilizers for home gardens. When these substances are dissolved as they are or in water, they become acidic, alkaline or neutral electrolyte solutions. These various home-use agents are commercially available in large quantities as products with safety precautions for use. In this way, we have found the most effective electrolyte solution for wet primary batteries when combined with aluminum metal from conductive powders and powders that are widely produced and sold and easily available at home. There must be.

  A simple experimental battery was prepared in order to find an effective agent as an electrolyte for a battery using aluminum metal as a negative electrode from household liquids in daily living environments. It takes a lot of processing to take out aluminum metal from the waste material of aluminum metal products, so fold the No. 5 cooking partition mold punched out aluminum foil that can be obtained and used as it is and sandwich it with horticultural aluminum wires and the negative electrode structure did. Moreover, what wound copper wire around the copper pipe or Bincho charcoal was used as the positive electrode structure. A simple tea cell was constructed by wrapping a negative electrode structure and / or a positive electrode structure using polyethylene tea bags and inserting the negative electrode structure and the positive electrode structure into a plastic container.

  A household electrolyte liquid was injected as an electrolytic solution into this simple experimental battery, and the open circuit voltage between the positive electrode structure and the negative electrode structure was measured, and the temporal transition of the open circuit voltage was examined. In addition, the transition of voltage and current was measured by connecting a load through which a current of 10 mA or more flows from the beginning. As a result, it was found that it was chlorinated alkaline detergents that produced a battery effect more effective than saline when combined with aluminum foil among household agents.

  Along with the investigation of the electrolyte solution of this battery, as a constituent material of the positive electrode that becomes the other electrode of the wet primary battery, Bincho charcoal, high temperature fired bamboo charcoal, stainless steel screw, carbon rod of single-type manganese dry battery, copper wire, copper pipe The copper plate was comparatively investigated.

  As a result of such investigations, if a chlorinated alkaline detergent containing hypochlorite / sodium hypochlorite is used as the electrolyte, and the copper material is a positive electrode structure, saline solution is used in a set of experimental batteries. It was found that an open circuit voltage exceeding 1.3 V, which is much higher than that obtained when the electrolyte was used, was obtained. However, with this set of experimental batteries, a high load voltage capable of lighting the red light emitting element cannot be obtained. Therefore, when two or more sets of experimental batteries having the same configuration are connected in series and the red light emitting elements are turned on, 1 mA is used. Although it has a smaller current, it has become possible to continue lighting for more than a year. However, in a set of experimental batteries, a combination of an electrolyte and an electrode that can obtain a voltage capable of lighting a red light emitting element for a certain period of time has not been found.

  In order to turn on the red light emitting element, the battery has a battery capacity of 10 mA or more at 1.8 V, and this ability needs to be sustained. The resistance value of the light emitting element as a load is 180 ohms at 1.8 V and 10 mA. In order to extract a large current with a high load voltage of the battery, it is necessary to reduce the internal resistance of the battery. In particular, it was estimated that the internal resistance of the electrolyte solution between the negative electrode and the positive electrode needs to be lowered. Therefore, an attempt was made to reduce the gap between the negative electrode and the positive electrode to increase the concentration of the electrolytic solution. In addition, an attempt was made to lower the specific resistance of the electrolyte by mixing a high concentration electrolyte in the polymer. When such a thick electrolytic solution is injected into an experimental battery using an aluminum foil as a negative electrode, a current of 100 mA or more flows at first, but it decreases to several mA in about 10 minutes. After that, the load voltage drops to around 1V, and a current of 1 to 2 mA can flow for more than a day. After the experiment, when the aluminum foil experimental battery operated in this way was disassembled, in each case, a much larger amount of white or brown paste than the volume of aluminum that reacted with the electrolyte and melted Alternatively, a crystalline product was generated.

  If the electrolyte concentration of the electrolyte is increased to reduce the internal resistance of the battery, and the electrode spacing between the positive electrode structure and the aluminum negative electrode structure is close, the tea wrapped around the positive electrode structure etc. to prevent short circuit The reaction product of aluminum is covered with the cloth of the sachet bag, that is, the aluminum foil surface of the negative electrode is covered with the film of the aluminum product, and the positive electrode structure surface and the aluminum foil surface of the negative electrode structure are obstructed from contact with the new electrolyte. Was in a state to be.

  When bamboo charcoal or Bincho charcoal fired at high temperature is used as the positive electrode structure, the electrolyte solution rises by capillary action in the gap that continues in the axial direction of the charcoal, and the copper wire part that is wound to take conduction at the upper part of the electrolyte surface Reaching and corroding the copper wire, the contact resistance between the Bincho charcoal positive electrode and the copper wire is remarkably increased, and the voltage becomes unstable. This phenomenon also hinders the battery voltage sustainability.

  In addition, when a copper tube or a copper plate is used as the positive electrode structure and a tea strainer bag is wound to prevent a short circuit with the negative electrode, when the chlorinated alkaline detergent is used as an electrolyte, the electrolyte encloses the positive electrode structure. The cloth of the bag goes up to the part that is on the liquid surface of the copper metal due to the capillary phenomenon, corrodes the copper metal that is exposed to the atmosphere and opens a hole, and the copper positive electrode structure becomes a consumable part. .

  In addition, when aluminum metal is used as the negative electrode structure, the use of a different metal in order to establish electrical continuity with the aluminum metal portion immersed in the electrolytic solution causes a problem in battery operation. Therefore, the same aluminum metal is used. However, in the case of an experimental battery configuration in which an aluminum foil is sandwiched between aluminum wires as the negative electrode structure, chlorine in the electrolyte reacts with the surface of the aluminum wire, and corrosion of the surface of the aluminum wire by chlorine is far away from the electrolyte surface. Propagation progresses to the tip of the aluminum wire in a short time, impairs the electrical contact of the part connected to the external circuit of the battery with a clip or the like, and inhibits the voltage sustainability of the battery.

  When aluminum metal was used as the negative electrode, chlorinated alkaline detergents were found as electrolytes suitable for battery action, but the reactive organisms of the electrolyte and aluminum remained on the surface of the aluminum metal as the negative electrode structure. In addition, the contact between the aluminum metal and the new electrolyte must be suppressed to avoid the phenomenon that impairs the battery operation. In addition, a phenomenon occurs in which the aluminum product is clogged in the tea strainer bag that encloses the copper tube of the positive electrode structure, preventing the movement of ions in the electrolyte. For this reason, the voltage current of a battery will fall in a short time. This problem and the propagation of the surface corrosion phenomenon of the aluminum wire connected to the negative electrode structure, the corrosion of the copper wire as the copper wire of the positive electrode structure or the Bincho charcoal, and the sustainability of the voltage and current of the battery are impaired. The problem must be avoided.

  Wet primary batteries combining electrolytes and aluminum metals, which are chlorinated alkaline cleaners (hereinafter collectively referred to as chlorinated alkaline antifouling / deodorizing / disinfecting / disinfecting / bleaching / cleaning agents as chlorinated alkaline cleaners). In order to find a method for maintaining a high load voltage and a large load current, a large amount of chlorinated alkaline detergent electrolyte is placed in a wide transparent container, and the negative electrode structure aluminum metal and the positive electrode structure are placed. It was inserted, and the mutual positional relationship, the open circuit voltage of this wet primary battery, and how the load voltage and the load current are related were measured. Moreover, the generation | occurrence | production of the bubble in the electrolyte solution of the aluminum metal surface which is a negative electrode structure, and the positive electrode structure surface was observed.

  The battery capacity expected as a wet primary battery is 1.8 V-10 mA or more for lighting one red light emitting element. When the battery capacity of the wet primary battery is about this level, it has been found that the wet primary battery does not depend much on the distance and positional relationship between the negative electrode structure and the positive electrode structure in the electrolyte. Also, a large amount of aluminum, which is the negative electrode structure, dissolved in the electrolytic solution does not necessarily lead to a large battery capacity. It has been found that only aluminum may melt while the voltage is low. When a sufficient amount of chlorinated alkaline detergents is placed in a large container, a battery is constructed, and the vicinity of the aluminum surface as the negative electrode structure is in contact with the electrolytic solution, bubbles are generated and the electrolytic solution is convected. ing. Moreover, in this case, the product formed by the reaction of aluminum with the electrolyte does not become a white-brown paste or powder, or a solid containing water of crystallization, dissolves and diffuses in the electrolyte, It turned out that it does not deposit on the aluminum metal surface as a negative electrode structure.

  Also, with a large container filled with a sufficient amount of electrolyte, which is a chlorinated alkaline cleaner, as a positive electrode structure, in addition to copper tubes and copper plates, stainless steel bolts, carbon bars for manganese batteries, Bincho charcoal, bamboo charcoal As a result of the comparison, in the electrolytic solution using chlorinated alkaline detergents, there is a drawback that when the positive electrode structure of the copper tube or the copper plate is used, there is a drawback that it is easily affected by changes in the electrolytic solution component. However, it was found that the load voltage of the battery was about 10% higher, which was most preferable. Stainless steel bolts and carbon bars for manganese dry batteries are not suitable because the voltage drops significantly when a load is connected.

  In the case of expecting a battery capacity of about 10 mA at 1.8 V in a wet primary battery in which a copper material is used for the positive electrode structure, the negative electrode structure is made of aluminum metal, and a chlorinated alkaline detergent is used as the electrolyte, Rather than considering the internal resistance of the battery due to the resistance of the electrolytic solution, bubbles generated on the surface of the aluminum metal that is the negative electrode structure rise in the electrolytic solution and are diffused from the electrolytic solution surface to the atmosphere. It is more important that the metal surface of aluminum, which is, maintain the battery action of aluminum metal by constantly maintaining new contact with the electrolyte circulating by convection. If convection circulation of the electrolytic solution occurs, the product resulting from the reaction with the aluminum metal electrolytic solution remains dissolved in the electrolytic solution, and does not deposit between the positive electrode structure and the negative electrode structure.

  When using aluminum metal as the negative electrode structure, copper metal as the positive electrode structure, and injecting chlorinated alkaline detergents as the electrolyte to make an instant wet primary battery, the component concentration in the electrolyte is higher However, the maximum voltage arrival time at the start-up of the wet primary battery is short, and the open circuit voltage, load voltage and load current of the wet primary battery also increase, but the aluminum metal of the negative electrode structure dissolves ineffectively without contributing to the battery action. Sometimes. Conversely, depending on the concentration of the electrolyte solution, which is a chlorinated alkaline detergent, it can be found that the time required to reach the optimum state of battery action of the negative electrode structure aluminum metal may take several hours with the load connected. It was. Even if a wide variety of electrolyte agents in the daily living environment are investigated, if this phenomenon is overlooked, it will be judged by a short-time measurement result, and an optimum electrolyte agent that can be used as an electrolyte cannot be selected.

  Aluminum waste from products using aluminum metal or aluminum alloy is one of the most common metal wastes emitted in daily living environments, so aluminum waste is readily available, but aluminum metal contained in aluminum products However, it is a part of a product having a complicated structure combined with other materials, and mechanical or chemical processing is required when aluminum metal is used as a waste material of an aluminum product. Therefore, the aluminum waste material is not always instantly and easily divertable as aluminum metal. Although it is easy to obtain the aluminum foil and the horticultural aluminum wire used in the above-mentioned experiment, it is not a main product among aluminum products and is not a waste material.

  Among the waste materials of aluminum metal or aluminum alloy products, aluminum containers for beverages and the like are easily available in large quantities and have standardized structural dimensions to some extent. Aluminum containers such as beverages are systems that are specially selected, collected, and reused for recycling aluminum containers after the contents are taken out by the consumer. Therefore, it is an aluminum scrap that can be most easily diverted in an emergency or emergency.

  However, the inner surface of an aluminum container such as a beverage is coated or laminated with a protective film to prevent it from reacting with and changing the quality of the beverage, so the inner surface of the empty aluminum container cannot be used as an aluminum metal as it is. Further, most of the outer surface of the aluminum empty container is laminated with a protective film, and at the stage of being sold as a product, printing and painting of product marks and explanations are performed. Therefore, normally, when using an aluminum empty container as an aluminum metal material, the organic film on the surface of the aluminum empty container is heated to a temperature close to the melting point of aluminum, as in the recycling system for recovered aluminum empty containers. It must be disassembled, stripped with chemicals, or mechanically polished and removed, requiring special industrial equipment and chemicals. Then, an aluminum empty container was not used as a battery electrode.

  A more detailed examination of aluminum containers for beverages and the like reveals that they have been standardized to some extent, but they are manufactured in many different structural dimensions. When trying to use these containers as used waste materials of aluminum containers for beverages, etc., immediately for the negative electrode of the battery without applying any special industrial treatment, it may be further limited to those of a specific structure. all right. The aluminum empty container is one in which the aluminum material constituting the container is exposed at a part of the bottom of the container due to the factor of the container forming method of the aluminum container. is there. In either case, the bottom part of the container, which is the main component of the container, and the cylindrical part that follows the bottom part are manufactured by deep drawing of a single aluminum plate and have a continuous structure.

  Two-piece aluminum cans and aluminum bottles are drawn while pressing the circular convex part at the bottom, which will be in contact with the floor after production, from both inside and outside of the aluminum sheet material, and extending the aluminum sheet outward from the convex part. Therefore, the cylindrical part following the bottom transition part and the bottom transition part on the outer side from the bottom circular convex part, the protective film laminated on the outer surface of the aluminum can made of an aluminum base plate by extension drawing processing does not stretch and peel off, At least the two-piece aluminum can and the outer surface of the bottom transition portion connected to the cylindrical portion from the circular convex portion of the bottom portion of the aluminum bottle remain exposed except for the case where coating or the like is applied again. The outer surface of the bottom concave portion inside the two-piece aluminum can and the bottom convex portion of the aluminum bottle has a portion where the protective film disappears during molding and a portion remaining. In addition, the outer surface of the upper lid of the two-piece aluminum can is laminated with an aluminum material, and after being molded, the material of the aluminum is excluding a part of the deeply drawn back inside the edge of the upper lid. Not exposed. Using a two-piece aluminum can or aluminum bottle empty container in which the aluminum metal material is exposed only on the outer surface of the bottom transition portion, and a chlorinated alkaline cleaning agent in a daily living environment, 1.8 V is set as one set. An instant primary battery that can sustain -10 mA or more for several hours must be realized.

  Although there are restrictions on the shape and storage and storage characteristics of dry batteries, mounting terminals are standardized, and there are many advantages in that the use position can be freely vertical and horizontal. In contrast, in an instant wet primary battery for the purpose of using only the battery action, when a liquid electrolyte is used, the battery is set up and used in a stationary state in principle. If the container has at least a small open port, gas generation is not a serious disadvantage, and if the aluminum negative electrode and the electrolyte are separated until needed, the problem of self-discharge can be avoided, which is feasible.

  The most popular structure of aluminum beverage containers, two-piece aluminum cans or empty containers, which are aluminum bottles, can be used without any mechanical processing, heat treatment or chemical treatment by factory equipment, or with minimal hand tools. The bottom convex part is cut using a nipper, and the bottom part is bent to the cylinder side by hand, and used as an aluminum negative electrode structure for an instant wet primary battery. The exposed area of the aluminum material metal at the bottom of the empty container which is a two-piece aluminum can or aluminum bottle is only about 1/30 of the total surface area of the aluminum structure inside and outside the aluminum empty container. In an empty container, which is a 350 ml two-piece aluminum can or aluminum bottle having the most standard volume, the exposed surface of the aluminum metal material has a small area of about 18 square cm. The material surface of the exposed aluminum metal material having a small area in one aluminum empty container is used as a negative electrode of at least the minimum unit battery. The material of the aluminum metal constituting the bottom surface of the two-piece aluminum can or aluminum bottle is an aluminum alloy containing 0.85 to 1.30% of JIS3004 standard magnesium (Mg) with good workability, and was used for the negative electrode of the battery. In this case, there is an advantage that the voltage is higher by several percent than that of pure aluminum.

  Further, when the structure of the two-piece aluminum empty can is examined in detail, the outer surface of the bottom transition part 26 of the two-piece aluminum empty can 22 is shown in FIG. An aluminum metal is exposed, and a tab 30 for opening the mouth of the can is attached to the upper lid portion 25 of the two-piece aluminum empty can 22. The upper surface of the dove 30 is covered with a protective film, but the tab 30 is subjected to a large molding process such as a hole for a finger. Therefore, the cross section of the cut surface of the aluminum plate is exposed on the back side of the tab 30 and can be easily connected to the aluminum plate of the dove 30 when sandwiched between clips. In addition, the tab 30 of the upper cover portion 25 of the aluminum can is attached to the upper cover portion 25 of the aluminum can with a deep protrusion, and after the tab is fitted, the protrusion is crushed and the tab is attached by caulking. . As a result, the caulking portion 31 also has a large processing, so that the protective film on the surface is removed, and the back side of the aluminum plate of the dove 30 and the upper lid portion 25 of the aluminum can are electrically connected. This state can be confirmed by measuring electrical continuity with the cut opening of the aluminum empty can 22 opened by pulling the tab.

  Further, the cylindrical portion 23 of the two-piece aluminum can 22 is shaped and sealed by double-tightening the upper portion of the cylindrical portion 23 and the aluminum can upper lid portion 25 after filling a beverage or the like in the product manufacturing process. Since this double winding closing portion 32 also has a high degree of processing, similarly, the upper lid portion 25 and the upper portion of the cylindrical portion 23 of the aluminum can are in direct contact with and electrically connected to the mating metal by this winding processing. Become. Eventually, the back side of the tab 30 and the outer surface of the bottom transition part 26 of the two-piece aluminum can 22 are electrically connected. This means that when the two-piece aluminum can 22 is immersed in the electrolyte, the lead wire of the aluminum material portion of the bottom transition portion 26 following the cylinder of the two-piece aluminum can 22 acting as a negative electrode is separated from the upper tab. It will extend to the back side. That is, the two-piece aluminum can itself has a structure having both an aluminum electrode that acts on the electrolytic solution and a conductive wire that is electrically connected to the aluminum electrode. In other words, the machining of cutting the bottom surface of the two-piece aluminum can and reconnecting the conductors is completely unnecessary.

  Further, the cylindrical portion other than the bottom transition portion that interacts with the electrolyte of the two-piece aluminum can is covered with a protective film or coating both inside and outside. This can be seen as a structure that suppresses a phenomenon in which aluminum metal corrosion due to components in the electrolyte rapidly propagates on the aluminum surface in the air. In addition, since the bottom transition portion 26 that interacts with the electrolyte of the two-piece aluminum can and the tab 30 that is connected to the external circuit by a clip or the like are separated, the exposed aluminum cross section on the back surface of the dove 30 is corroded by components of the electrolyte. Thus, a preferred negative electrode structure that can avoid poor contact is obtained. However, the connection of the double-clamping portion 32 of the two-piece aluminum can is rarely unstable due to variations in the manufacturing process of the two-piece aluminum can product or evaporation from the electrolyte when used as a negative electrode structure of a battery. 2 pieces of aluminum cans 22 are placed in the double wrapping portion 32 with a simple cutting twist with a nipper or the like before being put into the electrolyte solution. It is desirable to ensure that the continuity of the heavy winding portion 32 can be reliably maintained.

  In the case of a two-piece aluminum can 22, the bottom 24 is bent by hand to the cylindrical part 23 side to facilitate the action with the convective electrolyte solution, and the upper cover part 25 is also on the cylindrical part 23 side so that the tab 30 is upward. And the cylindrical portion 23 is flattened. In the case of a two-piece aluminum can that has been crushed in this way, a battery can be configured with a small amount of electrolyte when a flat container is used in accordance with its shape.

  In the case of an aluminum beverage bottle, the exposed bottom transition material of the aluminum metal material extends to the top of the bottle, which is the upper end of the aluminum bottle. By the way, the cross section of the aluminum material thin plate is exposed. This can be sandwiched between clips to establish continuity with an external circuit. In this way, even in an aluminum bottle, the lead wire with the aluminum material surface that acts as the negative electrode of the battery uses the bottle itself, and the lead wire is applied as a beverage product with a coating on the outer surface of the bottle or a protective film on the inner surface. It is protected and has a preferable structure in which the corrosion propagation phenomenon on the aluminum surface in the air hardly occurs. In the case of an aluminum empty bottle, the cylindrical portion is hard and is not easily crushed by hand. Even when the bottom surface is deformed, only the bottom surface needs to be inclined slightly toward the cylinder side.

  In the electrolyte, the bottom of the aluminum empty container is inclined or vertical rather than horizontal, which facilitates the convection of the electrolyte and the rise of bubbles. The reaction with the electrolyte can be maintained smoothly. Therefore, the entire aluminum empty container may be slightly tilted and immersed in the electrolyte without folding the bottom of the aluminum empty container. However, if the aluminum empty container is laid sideways and placed in the electrolyte, a two-piece aluminum empty can The tab of the aluminum bottle or the mouth end of an empty aluminum bottle approaches the electrolyte surface, the aluminum surface is corroded, and the connection point to the external circuit becomes poorly contacted. Avoid the method.

  A copper tube or a copper plate is used as the positive electrode structure. One or more copper tubes having a diameter of 8 to 10 mm and a thickness of 0.3 to 1 mm and a length of 40 to 120 mm, or a copper plate having a width of 20 to 50 mm and a length of about 250 mm and a thickness of 0.2 to 2 mm in a cylindrical shape A shaped one, a disc having a diameter of 40 mm or more, or a quadrangular shape having a side of 40 mm or more and having a surface area as large as possible that can be placed on the bottom surface of the battery container is used. The external surface area of the positive electrode structure, such as a copper tube, is such that the area on one side facing the aluminum empty container of the negative electrode structure is close to the area of the bottom transition part of the aluminum empty can that acts as the negative electrode of the battery.

  When partitioning with a sheet of insulating material to prevent the copper surface of the positive electrode structure from coming into contact with the aluminum empty container which is the negative electrode structure, for example, a draining net made of polyethylene having a mesh with a diameter of 1 mm or more Is set so that air bubbles generated on the copper surface of the positive electrode and the circulation of the electrolyte are not hindered. The copper material of the positive electrode structure is fixed to the battery container when possible. The copper material of the positive electrode structure should have a dimension that extends far above the electrolyte surface, or a dimension that sinks into the electrolyte, and if the copper material of the positive electrode structure sinks into the electrolyte, Soldering connection is made with a synthetic resin-coated electric wire that is not damaged, and the connecting portion and the electric wire tip are covered with water-resistant silicone resin or the like. A thick copper wire and a copper material of the positive electrode structure may be welded, pressed, and copper riveted. When the copper material of the positive electrode structure or the copper of the conductive wire to the copper material of the positive electrode structure is exposed near the electrolyte surface, it must be covered with a water-resistant silicone resin or the like.

  In the battery container of the present invention, after inserting the positive electrode structure, the aluminum empty container serving as the negative electrode structure is separated from the positive electrode structure by 1 mm or more, and most of the bottom transition part of the aluminum empty container is the battery container. The shape and size are such that a gap region can be secured so that the convection of the electrolytic solution reacting with the bottom transition portion of the aluminum empty container and the rising of the generated bubbles can be ensured. When inserting the aluminum empty container vertically without deformation, it is a circular container, and a spacer is put on the bottom of the container to separate the bottom of the aluminum empty container from the container bottom. When tilting without inserting the aluminum empty container, or when inserting the bottom part deformed, ensure a region where the electrolyte and bubbles flow between the battery container and the bottom transition part of the aluminum empty container as much as possible. A compact battery case is used. The depth of the battery container is such that the edge of the battery container is inserted so that the tab connected to the external circuit and the crimped portion holding the tab are not wetted by bubbles generated from the electrolyte and rising above the liquid level. The depth is 10 mm or more lower than the crimped portion of the piece aluminum empty can. In the case of an aluminum bottle, the dimensions are such that the edge of the container is 20 mm lower than the upper end of the bottle placed in the battery container.

  The electrolyte used in the present invention is one of sterilizing, antifungal, deodorizing, disinfecting, bleaching, and cleaning agents that are easily available in large quantities in daily living environments that are not industrial acids or alkalis. To do. Only sodium hydroxide is available at general pharmacies. A solution of sodium hypochlorite is commercially available as a disinfectant for pools and agricultural vegetables. In the present invention, among sterilizing, antibacterial, deodorizing, disinfecting, bleaching, and cleaning agents for household use that are sold in large quantities, especially chlorinated alkaline sterilizing / antifungal / deodorant containing hypochlorite and sodium hypochlorite.・ Use disinfectant, bleach and detergent as electrolyte. Some household cleaners include acidic cleaners, but when mixed with chlorinated alkaline cleaners, a large amount of chlorine gas is generated, which is extremely dangerous. Also, hydrogen peroxide bleaching agents, percarbonate cleaning agents, and the like are not used as the electrolyte of the battery of the present invention because they are almost ineffective.

  Chlorinated alkaline sterilizers / antifungals / deodorizing / disinfecting / bleaching / cleaning agents contain hypochlorite and sodium hypochlorite as main agents. Depending on the intended use of these cleaning agents, sodium hydroxide About 0.1% to 4% of caustic soda is added. In addition, a surfactant of sodium alkyl ether sulfate or alkylamine oxide is included.

  The present invention provides a battery container in which a positive electrode structure constituting a battery is inserted in advance and a conductor with a clip for connecting a direct current load that uses the direct current voltage current of the battery. Uses empty aluminum containers and household chlorine-based alkaline cleaning agents that can be easily obtained in the living environment, and when battery action is required in an emergency situation, instant opening, maximum open circuit voltage of 2 .02V, a wet primary battery with a battery capacity of 1.8V-10mA or more obtained by connecting a load for several hours, and is an emergency for light emitting devices for lighting, low-power communication devices, and electronic devices An emergency DC power supply can be provided.

  When a voltage of 3 V or more is required to light a white, green, or blue light emitting element, two or more sets of wet primary batteries of the present invention are connected in series to achieve a current of 10 mA or more at a high voltage of 3 V or more. A current can be obtained. If the load voltage is allowed to decrease to 1 V, a current of 100 mA or more can be obtained for several hours with a set of wet primary batteries of the present invention.

  When the wet primary battery of the present invention is continuously used and the battery action is reduced, either an aluminum empty container which is an exhausted negative electrode structure or a chlorine-based alkaline cleaning agent injected as an electrolytic solution or If both of them are replaced with new ones, the wet primary battery of the present invention can continuously take out a DC voltage current of 1.8 V-10 mA or more over several days.

  The only convenient tool for constructing the wet primary battery of the present invention is a nipper for making a cut if necessary in the bottom convex portion of the aluminum empty container. Bending and deformation of the bottom of the aluminum empty container and the upper lid are sufficient as long as they can be crushed by hand.

  When the battery action of the wet primary battery of the present invention is interrupted or stopped, the aluminum empty container of the negative electrode structure is taken out or the electrolytic solution is taken out. If the negative electrode structure aluminum empty container taken out when the battery action becomes necessary is inserted again or the electrolytic solution is injected, if the battery action has been made once, the optimum battery action is immediately generated. Can do.

  Prepare a thing in which a positive electrode structure is inserted into a battery container in advance, and when a direct current power supply of 1.8 V-10 mA or more is required in an emergency situation, an ordinary aluminum empty container in a daily living environment, Combined with chlorinated alkaline detergents, an instant wet primary battery is assembled to provide a battery that continuously supplies direct current to light-emitting elements for lighting and signs and low-power communication electronic devices for several hours.

  FIG. 1 is a front perspective view showing a first embodiment of an aluminum empty container battery according to the present invention.

  Positive electrode structures 11a and 11b made of a copper tube having a diameter of 10 mm and a thickness of 0.5 mm, in which a flat-shaped (transparent) battery container 13 made of polyethylene is wound with sheets 12a and 12b having a rough surface such as polyethylene drainage nets. Is inserted on both sides of the battery case 13 and, if necessary, the upper portions of the positive electrode structures 11a and 11b are pressed vertically with an adhesive tape (not shown) or the like and fixed vertically. When the battery action becomes necessary, for example, 350 ml of two-piece aluminum empty cans 2 for beverages are collected, and the upper lid portion 5 is pushed so that the tab 10 faces upward and bent to the cylindrical portion 3 side of the aluminum empty can 1. . Similarly, the bottom part 4 of the two-piece aluminum can 2 is bent to the same side of the cylindrical part 3. Further, the cylindrical portion 3 of the 2-piece aluminum can 2 is crushed flat. Nippers are used to prevent the two-piece aluminum can 2 from floating in the electrolyte, and to start the reaction between the aluminum in the bottom transition portion 6 of the two-piece aluminum can 2 and the electrolyte when the electrolyte is injected. Then cut in 9a and 9b. The two-piece aluminum can 2 that has been crushed and cut in this manner is fitted into the battery container 13 and, for example, a flat battery container is formed by utilizing the spring action of the bent bottom portion 4 of the two-piece aluminum can 2. 13 is fixed at a distance of 1 mm or more so as not to contact the positive electrode structures 11a and 11b. The upper portion of the two-piece aluminum can 2 may be fixed with an adhesive tape (not shown). The upper ends of the copper tubes 11a and 11b of the positive electrode structure are sandwiched between conductive wires with clips (not shown) to provide a conductive wire to the external circuit on the positive electrode side. The positive electrode structures 11a and 11b are connected in parallel. The portion that acts as the negative electrode of the two-piece aluminum can 2 that is the negative electrode structure is the bottom transition portion 6, and the tab 10 that is electrically connected to the bottom transition portion 6 is sandwiched between the lead wires with clips. The lead wire on the negative electrode side is made to be in contact with the aluminum exposed on the back surface of 10.

  FIG. 2 is a partially cutaway cross-sectional view of a two-piece aluminum can 22 having a portion where an aluminum material is exposed outside the bottom used as a negative electrode structure in the present invention. In FIG. 2, the outer surface of the bottom transition part 26 of the two-piece aluminum can 22 that has been extracted from the contents of a beverage or the like as a product and has become an empty container has already been exposed to aluminum metal when it is sold as a beverage product. ing. In the present invention, this aluminum surface is used as the negative electrode of the battery. The bottom transition portion 26 is electrically connected to the cylindrical portion 23, the double tightening portion 32, the upper lid portion 25, the tab crimping portion 31, and the tab 30 and sandwiches the dove 30 with a clip to which a lead wire of an external circuit is attached. And the aluminum of the bottom part transition part 26 used as a negative electrode of this invention of the 2 piece aluminum can 22 and an external circuit are electrically connected. The structure of the two-piece aluminum can 22 serves as a conducting wire extending to a position far away from the bottom transition portion 26 that interacts with the electrolyte solution with both the inner and outer surfaces protected by a protective film. The aluminum empty container battery of the present invention can be implemented by appropriately utilizing this configuration of the two-piece aluminum empty can 22.

  The reaction with the electrolytic solution at the bottom transition portion of the aluminum empty container can be maintained more smoothly when the bottom surface of the aluminum empty container is inclined or vertically peeled in the electrolytic solution than when the bottom surface is horizontal. However, it is better to tilt the aluminum empty container and insert it into the battery container. However, when the aluminum empty container is laid down and placed in the electrolyte, the tab of the two-piece aluminum can or the mouth of the aluminum empty bottle is the electrolyte surface. In this case, the aluminum surface of the portion is corroded and contact failure with a clip or the like connecting to an external circuit occurs.

  In FIG. 1 showing the first embodiment of the aluminum empty container battery, when the two-piece aluminum empty can 2 is deformed and flattened and inserted into a battery container 13 having a width of 30 mm and a rectangular shape of 120 mm, or an elliptical shape. The interaction between the bottom transition portion 6 where the aluminum material of the two-piece aluminum empty can 2 is exposed and the electrolyte is smoothly performed with a small amount of electrolyte, and bubbles rise and convection circulation of the electrolyte is facilitated. .

  In FIG. 1, which is an embodiment of the aluminum empty container battery 1 according to the present invention, when battery action is required in an emergency or emergency, for example, a two-piece aluminum can having a capacity of about 350 ml sold in the largest amount. Looking for empty cans, deformed and inserted into the battery container 13, looking for chlorinated alkaline detergents containing hypochlorite and sodium hypochlorite in the daily living environment, and liquid detergent As an electrolyte, 100 cc is added so that the liquid level is at the level indicated by the two-dot broken line 14 in FIG. This instant wet primary battery, aluminum empty container battery 1, uses a new two-piece aluminum empty can 2 and injects chlorine-based alkaline cleaners for drainage treatment containing 4% sodium hydroxide as the electrolyte. In this case, if a red light emitting element is connected as a load, a load voltage of 1.8 V or more is obtained within a few minutes after the electrolyte is injected, and the load voltage is changed from 1.9 V to V 1.95 V in 20 to 100 minutes. To rise. The open circuit voltage is 2.02 V at maximum. After this, while observing the transition of the load voltage, if the same electrolyte is gradually added up to 180 cc where the upper end of the bottom transition portion 6 of the two-piece aluminum empty can 2 is immersed, a current exceeding 15 mA at 1.9 V or more will be 5 A battery action that flows for more than an hour was obtained.

  In the aluminum empty container battery 1 of the present invention shown in FIG. 1, the case where the positive electrode structure has two copper tubes has been shown. However, either one of the copper tubes is possible, and conversely, three or more may be used. . The positive electrode structure may have a plate shape or a mesh shape. Sheets 12a and 12b, such as polyethylene drained nets wound around copper tubes, have a gap of 1 mm between the positive electrode structure and the two-piece aluminum empty can 2 as the negative electrode structure on the battery container 13 side. It is preferable not to use a sheet as long as it has a means for fixing it apart. The material of the flat battery container 13 made of polyethylene is not limited to polyethylene and may be other plastic materials or glass as long as it does not have pores by reacting with the electrolytic solution. The shape of the battery container 13 need not be limited to a flat shape.

  In the example of FIG. 1, when 180 cc of chlorinated alkaline detergents containing 4% sodium hydroxide are injected at a time, the reaction with aluminum is abrupt, and depending on the electrolyte containing a large amount of surfactant, Although the generated foam may overflow from the battery case 13, a current exceeding 40 mA can be supplied to the load at 1.9 V or more. In this case, since the voltage / current decreases within a few hours, all of the first electrolytic solution is discarded and replaced with a new electrolytic solution. Since the bottom transition part 6 of the aluminum empty can 2 is in a state favorable for battery action at the second time, a high load voltage is reached in a short time. However, when the electrolyte solution of chlorinated alkaline detergents containing the same 4% sodium hydroxide is repeatedly used, the bottom transition part 6 of the two-piece aluminum empty can 2 melts and has a hole in about 3 to 4 times. In that case, replace the two-piece aluminum can 2 with a new one.

  When a load requiring a larger current than the red light emitting element is connected to the aluminum empty container battery 1 of the present invention, for example, a load having a resistance value of about 10 ohms is connected, and chlorinated alkaline containing 4% sodium hydroxide is used. When 180 cc of cleaning agent is injected at a time, a current of 100 mA or more flows at a load voltage of 1.5 V, a current of 100 mA or more continues for 5 hours until the voltage drops to 1 V, and further 8 hours until it reaches 50 mA at 0.5 V Lasted. However, in this case, the bottom transition part 6 of the two-piece aluminum can 2 was perforated once.

  In the embodiment of FIG. 1 of the present invention, a new two-piece aluminum can 2 is used, and kitchen bleach, which is a chlorinated alkaline detergent for kitchens with a low content of sodium hydroxide, is used as an electrolytic solution, 180 cc at a time. The battery characteristics of the aluminum empty container battery 1 when injected will be described. If the red light emitting element is connected as a load from the beginning, the red light emitting element starts to emit light shortly after the first electrolyte injection, but the voltage rises slowly, and after 1 hour the load voltage current rises to 1.7 V10 mA, After 2 hours, it becomes 1.78 V-20 mA, and after 3 hours, it reaches 1.85 V-30 mA. Thereafter, the voltage gradually decreased, but the duration of 20 mA or more was 11 hours, and the duration of 10 mA or more was 20 hours.

  After that, when the red light-emitting element is continuously turned on as a load, the replacement of the electrolyte solution is repeated once a day by repeating replacement with a new electrolyte solution of chlorinated alkaline detergents that are the same kitchen bleach. The bottom transition portion 6 that reacts with the electrolyte of the two-piece aluminum can 2 that is the negative electrode structure gradually shifts to a state preferable for battery action, and the rise time of the voltage after the electrolyte replacement is shortened. In addition, the load voltage is also high, and a larger current can be obtained continuously. For example, after the seventh electrolyte injection, the rise of the load voltage current is remarkably fast, and a current of 10 mA or more begins to flow in 1 to 2 minutes, and after 10 minutes, the load voltage rises to 1.87 V and exceeds 40 mA. A current flowed, and then a current of 40 mA or more continued for 8 hours. A current of 20 mA or more could be continued for 22 hours.

  In this way, the current is continuously passed through the load by replacing the electrolytic solution of chlorinated alkaline detergents, which are the same kitchen bleach, once a day. After the seventh continuous energization, the negative electrode of this aluminum empty container battery 1 When the bottom transition part 6 of the two-piece aluminum can 2 as a structure was examined, the aluminum surface was melted and uneven, but no holes were formed yet.

  More preferably, the aluminum surface of the concave portion 8 inside the laminated protective film remaining on the surface of the concave portion 8 which is the center of the bottom portion 4 of the two-piece aluminum can 2 is from the bottom transition portion 6 side. A state of adding to the battery action is caused by the soaked electrolytic solution, like the aluminum in the bottom transition portion 6. This has the same effect as the area of the bottom transition portion 6 acting as a battery is widened. By this phenomenon, the battery capacity of the aluminum empty container battery 1 of the present invention is gradually increased every time the electrolytic solution is exchanged until the bottom transition portion 6 is melted and the hole is opened.

  When the battery action of the aluminum can container battery 1 of the present invention is continued while changing the electrolyte, the bottom transition portion 6 of the 2-piece aluminum can 2 and the cylindrical portion of the 2-piece aluminum can 2 From the boundary of 3, the lower aluminum of the coating film on the outer surface of the cylindrical part 3 starts to react with the electrolytic solution, and the electrolytic solution penetrates into the back side of the coated film of the cylindrical part 3, and the aluminum of the cylindrical part 3 there Since the surface is added to the battery action, if the battery action of the aluminum empty container battery 1 is continued while changing the electrolyte, the bottom transition part 6 and the bottom recess 8 are melted and disappear until the cylindrical part 3 Aluminum may continue to function as a battery.

  In the aluminum empty container battery 1 according to the first embodiment of FIG. 1 of the present invention, using a kitchen bleach having a low sodium hydroxide content as an electrolyte, while replacing the electrolyte once a day, If the operation of supplying a current of 20 mA or more to the load is continued, the capacity of the battery will decrease after about 10 times, so it remains undissolved in the bottom transition portion 6 of the 2-piece aluminum can 2. Even if there is a part, it is desirable to replace it with a new 2-piece aluminum can.

  Table 1 shows typical commercially available chlorine-based alkaline antifungal / deodorizing / disinfecting / disinfecting / bleaching / cleaning agents that can be used as the electrolytic solution for the aluminum empty container battery of the present invention. Table 1 also describes a sterilizing detergent that contains components contained in commercially available chlorine-based alkaline antifungal, deodorizing, disinfecting, disinfecting, bleaching, and cleaning agents alone as the main agent. Hypochlorite and sodium hypochlorite are commonly included in the chlorinated alkaline antifungal, deodorant, disinfectant, disinfectant, bleach, and detergent used as the electrolyte of the aluminum empty container battery of the present invention. Yes, it contains surfactants alkylamine oxide or alkyl ether sulfate ester sodium and sodium hydroxide in a small amount to about 4%, and it is sold as a different product according to the purpose of use in the home. Yes.

  In order to select commercially available chlorine-based alkaline antifungal, deodorant, disinfecting, disinfecting, bleaching and cleaning agents that can be used as the electrolyte of the aluminum empty container battery of the present invention, it is displayed in the product description of the chlorine-based alkaline cleaning agents. In combination with these components, the effects of the contained components when used as the electrolytic solution of the aluminum empty container battery of the present invention were examined.

  A single detergent containing a surfactant as a main component cannot be used as an electrolytic solution for an aluminum empty container battery of the present invention at an open circuit voltage of about 0.5 V, including when mixed with water. Even when an aqueous solution of several percent of sodium hydroxide alone is used as the electrolytic solution of the aluminum empty container battery of the present invention, the open circuit voltage is 1.5 V or less, and the aluminum of the negative electrode is merely wasted. In the case of an aqueous solution of sodium hypochlorite, when the electrolytic solution of the aluminum empty container battery of the present invention is used, the open circuit voltage is close to 1.6 V and wasteful dissolution of aluminum is small. A set of open circuit voltages will drop below 1V. In an electrolytic solution in which sodium hydroxide is added to an aqueous solution of sodium hypochlorite with a few percent, the load voltage becomes 1.8 V or more. However, if the concentration is high, aluminum is vigorously dissolved, and aluminum is dissolved in a short time. In an electrolyte solution in which sodium hydroxide is added to an aqueous solution of sodium hypochlorite and a small amount of a surfactant is added, there is a disadvantage that a large amount of bubbles are generated, and the maximum load voltage is slightly lowered. Dissolution of the water becomes gentle and a relatively constant current can flow for a long time. In the electrolytic solution in which sodium hydroxide and a small amount of surfactant are added to this aqueous solution of sodium hypochlorite, the deposition of aluminum reactive organisms on the aluminum metal surface is suppressed, and the aluminum reactive organisms are solid or crystalline. Prevents a paste-like product containing water and promotes diffusion of aluminum reactive organisms in dissolved form in the electrolyte.

  After all, as an electrolyte for wet batteries using aluminum metal as a negative electrode, a commercially available chlorine-based alkaline antifungal, deodorant and deodorant solution containing a small amount of sodium hydroxide and a surfactant in hypochlorite / sodium hypochlorite. Bacteria, disinfection, bleaching, and cleaning agents are most suitable, so use commercially available chlorine-based alkaline antifungal, deodorant, disinfecting, disinfecting, bleaching, cleaning agents listed in Table 1 or agents containing similar ingredients Supa is enough.

  When the battery action of the aluminum empty container battery 1 of the present invention is temporarily stopped, the reaction between aluminum and the electrolyte continues even when the load is removed and the current is zero, and the aluminum empty container 2 of the negative electrode structure is maintained. Therefore, it is desirable to discharge the electrolyte if possible. The battery container may include an electrolyte outlet and a valve.

  The instant wet primary battery of the present invention is not a battery that can obtain a constant voltage and current at the same time as a load connection like a manganese dry battery, but any of the chlorine-based alkaline antifungal, deodorant, sanitizer, disinfectant, By using a bleaching / cleaning agent as the electrolyte of the battery of the present invention, a set of aluminum empty container batteries of the present invention using one aluminum empty container as the negative electrode structure, 1.8 mA or more and 10 mA or more A current is obtained continuously for several hours or more.

  FIG. 3 is a sectional view showing a second embodiment of the aluminum empty container battery according to the present invention.

  A positive electrode structure 51a of a copper plate or a perforated copper plate with a conducting wire 54a attached in advance is placed on the bottom of the cylindrical battery container 53, which is an insulator, and an electrolyte and air bubbles freely pass through it made of plastic such as polyethylene. A net 52a for draining the drainage can be laid, a plastic spacer 55 is placed on the net 52a, and an aluminum empty container as a negative electrode structure is placed thereon. FIG. 3 showing a second embodiment of the present invention shows a case where an aluminum empty bottle 42 whose bottom is not bent is inserted. In addition, the spacer 55 supports the bottom recess 48 of the aluminum empty bottle 42 which is the negative electrode structure with as small an area as possible, and between the bottom of the aluminum empty bottle 42 and the copper plate 51a and net 52a of the positive electrode structure. A gap of several millimeters or more is secured, and the flow of the electrolyte and the bubbles generated in the electrolyte is prevented from rising from the center of the bottom of the aluminum empty bottle 42 along the outer peripheral direction and along the outer surface of the cylindrical portion 43 of the aluminum empty bottle 42. For example, it is shaped like a gas stove. Cuts 49a and 49b at 1 to 4 places are made in the convex portion 47 at the bottom of the aluminum empty bottle 42 with nippers. Thus, when the electrolytic solution is injected, the electrolytic solution also enters the inside of the aluminum empty bottle 42, and the aluminum empty bottle 42 does not float. In addition, the cuts 49a and 49b inserted into the bottom convex portion 47 of the aluminum empty bottle 42 serve as a starting point for the reaction between the negative electrode aluminum and the electrolytic solution when the electrolytic solution is injected, and have an effect of shortening the voltage rise time. . The aluminum empty bottle 42 does not need to be deformed, but when possible, when the bottom of the aluminum empty bottle 42 is tilted by about 45 degrees by pressing the cylindrical portion of the bottle, the voltage rise time after the electrolyte is injected Becomes faster. A cross section 50 of the aluminum metal material thin plate forming the bottle container facing downward is exposed outside the upper end of the bottle mouth of the aluminum empty bottle 42 as the negative electrode structure. This is sandwiched between cribs with a lead wire and used as a lead wire to an external circuit.

  In the aluminum empty container battery 41 of FIG. 3 which is the second embodiment of the present invention, the battery container 53 is a container made of polyethylene or polypropylene which is not affected by a chlorinated alkaline cleaning agent, or a glass container. When the battery container 53 is used in a state where the aluminum empty container is left standing without being deformed, the battery container 53 has an inner diameter that is about 1.2 times the diameter of the cylindrical part of the aluminum empty container and is 1 times the height of the aluminum empty container. A container having a depth not less than / 2 and not more than the height of the aluminum empty container. When a large amount of foam is generated from the electrolyte using a container deeper than the height of the aluminum empty container, the foam overflows to the bottle mouth and dove of the aluminum empty container, and the aluminum surface of the part corrodes, It is necessary to prevent the contact of the clip connected to the external circuit from becoming unstable. In some cases, a container that receives the bubbles overflowing outside the battery container while holding the depth of the battery container to about 80% of the aluminum empty container is used. When the aluminum empty container 42 is inserted as it is, a spacer 55 is always inserted in order to secure a reaction gap with the electrolyte at the bottom of the aluminum empty container 42, but the bottom of the aluminum empty container 42 is tilted without deformation. If the bottom part is bent or the bottom part is bent, the spacer may be omitted if a means for holding the battery container and the aluminum empty container in such a shape position is provided.

  In FIG. 3, which is the second embodiment of the present invention, a circular tube 51b made of a copper material is another embodiment of the positive electrode structure. The lead wire 54b is attached to a copper tube that is larger than the diameter of the aluminum empty bottle 42 and does not hinder the flow of the electrolyte and bubbles, for example, the outer diameter of the aluminum empty bottle 42 +15 mm in inner diameter and 10 to 60 mm in height. Thus, a positive electrode structure is formed and inserted outside the mesh 52a. The positive electrode structure 51b may not be formed by rounding the tube, but may be an arc shape obtained by dividing the circular tube in the axial direction or a rectangular copper plate bent into an arc shape. If the bottom convex portion 47 of the aluminum empty container has nippers 49a and 49b, lead wires 54c and 54d are connected in advance to a copper tube having a diameter of about 10 mm as a further positive electrode structure, and a plastic mesh The positive electrode structures 51c and 51d wound with 52c and 52d may be put into an empty container from the upper opening of the aluminum empty bottle 42. When the copper tube 51c of the positive electrode structure is short and sinks in the liquid, the lead wire 54c uses a water-resistant lead wire, and the connection portion between the copper tube and the lead wire is sealed with a waterproofing agent. The copper positive electrode structures 51a, 51b, 51c, 51d shown in FIG. 3 have a certain contact area with the electrolyte and do not directly contact the aluminum empty bottle 42 of the negative electrode structure. What is necessary is just to be comprised so that it may not inhibit that the electrolyte solution which contact | connects the surface of a structure, or the bubble generate | occur | produced in electrolyte solution flows. The copper positive electrode structures 51a, 51b, 51c and 51d may be inserted in parallel as shown in FIG. 3 or may be connected in parallel. To some extent, when the surface area of the positive electrode structure in the electrolyte is large, the battery voltage also increases. The material of the battery container 53 can be made of a copper material. Further, a spacer 55, a positive electrode structure, and a negative electrode structure are provided as a structure including, for example, a holder for supporting and fixing the aluminum empty bottle 42 of the negative electrode structure and the positive electrode structures 51a, 51b, 51c, 51d to a plastic container 53 in a preferable positional relationship. The nets 52a, 52c and 52d for preventing the close contact with the body may be omitted.

  In the case of an emergency, if there is a plastic battery container 53 in FIG. 3 that has a radial pleat that prevents deformation on the bottom of the plastic bottle for beverages, a knife is placed in the middle from the middle of the plastic bottle. The aluminum empty container 42 is inserted without removing the spacer 55 by cutting with a scissor or the like, and an anode structure 51c of, for example, a copper tube is inserted from the upper opening of the aluminum empty container 42. The anode structure 51c is an aluminum empty bottle. It is hung by the conducting wire 54c so that it may become a position away from the inner bottom of 42. If the configuration in which the electrolytic solution 56 is injected into this, the bottom of the aluminum empty container 42 does not adhere to the bottom of the PET bottle over the entire surface, and the electrolyte and bubbles in contact with the bottom of the aluminum empty container 42 can move radially. Therefore, as a simple battery container 53 for 2 to 3 days, it is possible to divert such a plastic bottle with a radial deformation prevention crease on the bottom.

  Although FIG. 3 shows the case where an aluminum empty bottle 42 is used as the negative electrode structure of the aluminum empty container battery 41, the bottom part of the two-piece aluminum empty can is used as it is without bending, and the upper lid part of the two-piece aluminum empty can If the positive electrode structures 51c and 51d are inserted from the mouth of the can opened by raising the tab, it can be carried out in exactly the same manner as in the case of an empty aluminum bottle.

In the configuration of FIG. 3 showing the second embodiment of the present invention, an electrolytic solution 56 is poured into the aluminum empty container battery 41 so that, for example, the aluminum empty bottle 42 is immersed in the half electrolytic solution. When the aluminum empty bottle 42 of the negative electrode structure reacts with the electrolytic solution 56, bubbles may accumulate below the recess 48 of the aluminum empty bottle 42, but the bottom transition portion 46 of the aluminum empty bottle 42 that reacts with the electrolytic solution Since the shape is inclined upward toward the outer circumferential direction,
This can be carried out without hindering the reaction with the electrolytic solution.

  In FIG. 3, an aluminum empty bottle 42 having a capacity of 350 ml is used, and the household drain outlet pipe cleaning agent, which is a chlorinated alkaline cleaning agent containing 4% sodium hydroxide, is used as the electrolytic solution 56 as it is. When injected, an open circuit voltage of 2.0 V was obtained as an instant wet primary battery, and a battery of 1.85 V-10 mA or more could be maintained for 14 hours.

  The aluminum empty container battery 41 of FIG. 3 according to the second embodiment of the present invention has a spacer 55 inserted between the bottom of the battery container 53 and the bottom of the aluminum empty bottle 42 which is the negative electrode structure. Since the gap in which the liquid and bubbles move and convect is secured, battery characteristics similar to those of the aluminum empty container battery 1 shown in Example 1 of FIG. 1 of the present invention can be obtained.

  In the aluminum empty container battery 41 shown in FIG. 3, the chlorinated alkaline cleaning agents shown in Table 1 are used as the electrolytic solution, and the electrolyte solution injection, additional injection, exchange, exhaustion and replacement of the aluminum empty container, etc. If the embodiment is carried out in accordance with the embodiment of the aluminum empty container battery 1, almost the same battery action as that of the aluminum empty container battery 1 of FIG. 1 can be obtained.

  FIG. 4 is a partially cutaway perspective view showing another embodiment of the aluminum empty container battery of the present invention.

  Positive electrode structures 71a, 71b, 71c, 71d made of, for example, a copper tube having a diameter of 10 mm or a body rod, with conductor wires 74a, 74b, 74c, 74d attached to external circuits at the four corners of the plastic battery container 63 are vertically provided at the four corners. Attach to. Near the center of the positive electrode structure attached to the battery container 73, plastic bottom meshes 72a and 72b are inserted so that the negative electrode structure does not come into contact with the bottom. When the upper lid portion is bent to the cylindrical portion side to crush and thin the can, a plurality of cuts 69a are inserted along the circumference into the bottom convex portion of the two-piece aluminum empty can 62a and immersed in the electrolyte solution. Enters the two-piece aluminum can 62a so that it does not float. Further, in the embodiment of FIG. 4, a plurality of two-piece aluminum cans 62a, which are negative electrode structures, are wound around a tab of a two-piece aluminum can 62a with a copper wire 76a wound for connection to an external circuit. The three conductors 76a, 76b, and 76c wound around the tabs of the two-piece aluminum empty cans that are arranged side by side in the center of the battery container 73 are put together from the three aluminum empty containers. Connect in parallel as conductors.

  The battery container 73 has the minimum vertical and horizontal dimensions so that three crushed two-piece aluminum cans can be separated from the copper tube of the positive electrode structure by at least 1 mm. The depth of the battery container 73 is a two-piece aluminum can 62a. 62b, 62c in order to prevent the generated bubbles from overflowing from the opening of the battery container 73 when an amount of the electrolyte solution is poured so that the upper ends of the bottom transition portions 66a, 66b, 66c bent in the vertical direction are immersed. The outer diameter of the bottom transition portion 66a that reacts with the electrolyte of the two-piece aluminum can 62a is about 1.5 times the outer diameter.

  Among the chlorinated alkaline detergents used as the electrolytic solution in the present invention shown in Table 1, a chlorinated alkaline detergent for pipe cleaning containing 4% sodium hydroxide is prepared as the electrolytic solution, and battery action is required. In this case, the electrolyte solution is 200 to 300 cc so that the liquid level is slightly lower than the liquid level indicated by the two-dot broken line 77 in the drawing in which about 1/3 of the bottom transition portion 66a of the two-piece aluminum can 62a is immersed. inject. If a red light emitting element is connected as a load in advance, it becomes 1.9 V or more in about 10 minutes, and a current of 15 mA or more flows. The voltage and current also gradually increase, and a load voltage of 1.97 V and a load current of 20 mA or more are obtained. The unloaded open circuit voltage at this time was 2.0V. When the load voltage decreases in continuous operation, the electrolyte is added in increments of about 30 to 50 cc. The addition of the electrolytic solution is repeated until the upper end of the bottom transition portion 66a where the aluminum material of the two-piece aluminum empty can 62a in which the liquid surface is bent and becomes vertical in the electrolytic solution is exposed is immersed. As a result, the battery action with a load current of 15 mA or more was able to continue for 5 days at a load voltage of around 1.85V.

  Injecting the amount that the bottom of the aluminum empty container is completely immersed from the beginning, the open-circuit voltage does not change at 2.02V, but in the case of a new aluminum empty container and a new electrolyte, the load voltage becomes 1.97V or more, The load current also flows over 30 mA, and a large current lasts for several hours. However, bubbles may suddenly occur due to the action of the surfactant contained in the commercially available chlorinated alkaline detergents and overflow from the container, so another container for receiving the bubbles is placed outside the battery container 73.

  In the configuration of FIG. 4 showing the third embodiment which is an aluminum empty container battery of the present invention, the conductors 76a, 76b such as a two-piece aluminum empty can 62a, etc., with the copper electrodes of the four positive electrode structures being connected in parallel, 76c is separated one by one, and a two-piece aluminum can 62a, etc. is sandwiched again so that a plastic mesh is sandwiched between them and connected to the negative terminals of three load elements not shown in the figure. If the positive terminals of the three independent load elements are collectively connected in parallel with the four conductors 74a and the like of the structure being bundled, for example, three red light emitting elements can be lit independently. Conversely, the four lead wires 74a, 74b, 74c, and 74d on the positive electrode structure side are independently connected to the four positive electrode terminals of the four red light emitting elements while the two two-piece aluminum cans on the negative electrode structure side are connected in parallel. Connected to the three negative electrode terminals of the four red light emitting elements together and connected in parallel to the three 2-piece aluminum can side conductors, the four independent red light emitting elements can be made to emit light independently at the same time. Can do. Of course, the aluminum empty container battery 61 of FIG. 4 showing the third embodiment of the present invention can be operated by simply connecting four or more red light emitting elements in parallel.

  In the aluminum empty container battery 61 of FIG. 4, as a result of continuing the battery operation to energize the load, the load voltage decreased to 1.75 V or less and the load current also decreased to 5 mA or less, but the electrolyte level increased. If additional injection of the electrolytic solution is not possible, a new electrolytic solution may be replaced. On the other hand, when the bottom transition part, bottom recess, or deformed cylindrical part of each 2-piece aluminum can has not melted, but the electrolyte component still seems to remain, the new 2 -Battery action can be easily maintained by replacing the aluminum can.

  In the embodiment of FIG. 4 of the present invention, an aluminum empty container is formed on the bottom of the battery container without bending and deforming the bottom part of the aluminum empty container which is a two-piece aluminum can or an aluminum empty bottle as a plurality of negative electrode structures. If a plurality of spacers supporting the bottom part away from the bottom of the battery container or a mesh-like slat board having the same shape as the container bottom part is put and an aluminum empty can or an empty bottle is placed thereon, the open circuit voltage is 2 0.02V, but the voltage when the load is connected according to the number of aluminum empty containers inserted at the same time and connected in parallel approaches the open circuit voltage, and when the number of aluminum empty containers is large, the current of 50 mA or more is maintained. Can be obtained. When a means for fixing the aluminum empty container to the battery container is provided, it can be carried out without cutting the bottom convex portion of the aluminum empty container with a nipper.

  The aluminum empty container battery of the present invention is not a product in which the electrolyte and the negative electrode structure are manufactured as an electrolyte or a negative electrode of a wet primary battery, but for products manufactured for other purposes or for product sales. Waste that is a container. Therefore, they are optimized for dimensional weight and not high capacity like industrially produced manganese dry batteries and alkaline dry batteries. In addition, it is difficult to display the performance of the battery action with the nominal voltage and the nominal capacity, and to specify the discharge capacity and the discharge capacity with respect to the load resistance.

  In the aluminum empty container battery of the present invention, if the load is energized after starting the battery action with a new aluminum empty container and a new electrolyte, the battery capacity gradually increases to a certain level. In the aluminum empty container battery of the present invention, the maximum open circuit voltage at no load is almost 2.02 V in all cases, but the apparent internal resistance of the battery depends on the resistance value of the electronic device as a load. It varies from 5 ohms to 100 ohms in approximately 24 hours after each electrolyte injection. The aluminum empty container battery of the present invention is most suitable for use conditions such as lighting of a red light emitting element that requires a small current of 20 to 30 mA for one night at about 1.8 V higher than 1.5 V of a manganese dry battery. ing. When a constant voltage circuit is combined with the aluminum empty container battery of the present invention and a low-power electronic device requiring 10 to 20 mA at about 1.8 V is connected as a load, the operation lasting for the longest time can be expected. For a load that requires a current of 100 mA or more in the vicinity of 1.5 V, which is the same as the manganese dry battery, the voltage drops in a short time and the continuous use time is shortened. Conversely, in the case of a load that operates intermittently, such as an automatic flashing red light emitting element, the flashing operation can be performed by leaving it outdoors for two months.

  If two sets of aluminum empty container batteries of the present invention are connected in series, the open circuit voltage becomes 4V, and when a white light emitting element is connected, a sufficient current flows when the load voltage is 3V or more, and it can be lit continuously for one night. . If the aluminum empty container batteries of the present invention are connected in series and parallel, a load voltage load current of 4 mA or more and 50 mA or more can be obtained. However, there are variations in the continuous discharge characteristics of each aluminum empty container battery, and the voltage increases according to the number of combined aluminum empty container batteries, such as dry batteries, and the current according to the number connected in parallel. The capacity does not increase proportionally, but the battery with strong battery action in the combined aluminum empty container battery is made up to compensate for the battery with weak battery action, so that the voltage and current are gathered at a smaller value. The voltage current is lower than the voltage current corresponding to the number of the aluminum empty container batteries of the present invention connected in series and parallel. However, in return, the combined battery has the effect of suppressing voltage and current fluctuations against load fluctuations. In the aluminum empty container battery of the present invention, about 4 sets are practically connected in series, and about 2 to 3 sets are practically connected in parallel.

  The aluminum empty container battery of the present invention can be used by repeatedly producing and selling a positive electrode structure and a battery container that can be used repeatedly. Chlorinated alkaline detergents used as a consumer, who need a direct current battery action of 1.8V-10mA or more in an emergency situation, procure it by themselves from the daily living environment. It is an instant wet primary battery that can be generated. The dimensional volume is large, the density is not as high as the manganese dry battery, and the electrolyte is liquid, so the way to place the battery is limited to the vertical placement, but the venting port and the lead wire for the positive and negative electrodes above the battery container If it is attached, the battery container can be covered to prevent rainwater from entering and used outdoors.

  Table 2 shows an example of battery characteristics obtained with the aluminum empty container battery of the embodiment of FIG. 1, the embodiment of FIG. 3, and the embodiment of FIG.

  In FIGS. 1, 3 and 4 showing the embodiment of the aluminum empty container battery of the present invention, the aluminum empty container used as the negative electrode structure is mainly a two-piece aluminum can or an aluminum empty bottle having a size of around 350 ml. The case where it is used is shown, but there are two-piece aluminum cans or aluminum empty bottles having an aluminum material surface exposed at the bottom transition part, from a small one of about 130 ml to a large capacity of 1000 ml or more. Even these aluminum empty containers having different dimensions can be used as the negative electrode structure of the aluminum empty container battery of the present invention as long as the aluminum material is exposed at the bottom transition portion. In the case of an aluminum empty container having a large capacity, the area of the bottom transition portion also increases, and therefore, when used as the aluminum empty container battery of the present invention, a larger current is easily obtained.

  In order to turn on the white and green-blue light emitting elements, at least two sets of the aluminum empty container batteries of the present invention must be connected in series. Therefore, a battery container in which two sets each loaded with a positive electrode structure are combined. . In addition, a clip holder mechanism is configured on the battery container side to be held by holding the searched aluminum empty container. Furthermore, if necessary, the light emitting element as an illuminating lamp is integrated with the battery container, and the light emission is combined with the connection cord to the battery, the clip of the two-piece aluminum empty can tab, or the clip cord that conducts with the drinking mouth of the aluminum empty bottle. It can also be prepared as an element lighting device.

  In the practice of the aluminum empty container battery of the present invention, the chlorinated alkaline detergents used as the electrolytic solution can be diluted with water and used as the electrolytic solution, but in the present invention, in most cases, commercially available products are used as they are. Therefore, the safety precautions for the human body among the precautions on the label of chlorinated alkaline detergent products are strictly observed. Avoid mixing with acidic agents and alcohol that may generate dangerous chlorine gas. Since the stock solution is handled, never touch the skin.

  The remaining portion of the aluminum empty container that has been used as the aluminum empty container battery of the present invention is washed with water and returned to the aluminum empty container collection and recycling system. The electrolyte that has been used as a battery contains paint on the surface that is removed from the aluminum can as a product, and the polyethylene film that has been laminated inside the can, so it is combustible separately from the solution. Treat as dust. The electrolyte is originally an antibacterial, deodorant, disinfecting, disinfecting, bleaching, and cleaning agent for kitchens, bathrooms, etc., but some agents are specified to be diluted more than 100 times with water. is there. In the waste liquid after being used as the electrolyte of an aluminum empty container battery, the first antifungal, deodorant, disinfecting, disinfecting, bleaching, and cleaning agent components have almost disappeared by reacting with aluminum, but it is liquid for safety. The electrolyte waste solution is diluted with water and run into sewage for treatment. In the waste liquid of the electrolytic solution used as the battery, reactive organisms of aluminum and chlorinated alkaline detergents are dissolved. These products are compounds of aluminum chloride, hydroxide, and sodium, and are originally a large amount of aluminum compounds in the soil, and are not dangerous to humans, animals and plants unless they are specifically concentrated. If the waste solution of the electrolyte used in the aluminum empty container battery of the present invention is left as it is, an aluminum compound precipitates. In that case, the liquid component is discarded by flowing into sewage, and the crystal solid component is disposed as dust. . If it is not concentrated too much, it may be returned to the soil as it is. The gas generated during the operation of the aluminum empty container battery of the present invention is first bubbled by the effect of the surfactant on the electrolyte surface, and then the bubble is repelled and the gas is diffused into the air. Unless the bubbles are abnormally generated and intentionally ignited, the main component of the electrolyte is water and there is no danger of ignition.

  The aluminum empty container battery of the present invention is a light emitting device for lighting or marking that is produced by manufacturing a battery container with a positive electrode structure installed in a factory and connected to an external load, and is lit by the battery action of this aluminum empty container battery It is sold as an emergency product in combination with a lighting device or a power connection line for a low-power electronic device that requires DC voltage and current.

The chlorinated alkaline detergents used in the aluminum empty container battery of the present invention are sold as emergency emergency equipment together with the aluminum empty container battery device as a more concentrated electrolyte solution. If it is procured and the concentrated electrolyte is diluted with water and injected, the implementation becomes easier. Since the minimum amount of electrolyte required for the aluminum empty container battery of the present invention is about 50 cc, it is sealed in polyethylene in a bag and attached to the bottom of the aluminum empty container battery device. When necessary, an empty aluminum container may be inserted, the polyethylene bag may be broken, and the electrolyte solution may be discharged.
Since the electrolyte waste liquid of the aluminum empty container battery of the present invention is almost harmless if diluted with water, if the aluminum empty container battery container of the present invention is a battery container having a structure in which rainwater does not enter directly, the countryside, agricultural road, It can be used as a battery for a marker lamp or the like in which an automatically flashing light emitting element is allowed to stand for one month outdoors in Yamano. When a road signal device is damaged due to a power failure after an earthquake or flood and there is a power failure, the aluminum empty container battery according to the present invention can be turned on if there is a marker lamp of a light emitting element. The aluminum empty container battery of the present invention has no energy density and handling convenience as solar cells, lead-acid batteries, and dry cells, but is unattended at the shrines and temples, the back of buildings where sunlight does not reach, outdoor tents It is useful as a direct current power source for light emitting elements for simple lighting instead of candles in places such as caves where oxygen deficiency and fire are a concern. It can be used as a DC power supply for ceremonial lighting, decoration lighting, table candles, crime prevention lights around houses, and sensor electronics for crime prevention. Aluminum empty containers are a valuable resource to be recycled, but if there are situations where aluminum containers can be obtained as products in overseas living environments, carry used aluminum empty containers and chlorinated alkaline cleaners. In mountainous areas, it can be used as a DC power source for communication and signal equipment when necessary.
