First, an inorganic industrial chemical that generates hydroxide ions) is first reacted with an aqueous inorganic acid such as phosphoric acid, and then secondarily reacted with an aqueous organic acid such as citric acid to produce a composition having an electromotive force. The present invention relates to a technique for generating electrical energy by using this composition for an anode member and laminating a cathode member via a separator having ion exchange ability.

  In addition to primary batteries such as dry batteries, secondary batteries such as rechargeable storage batteries are routinely used as power sources for portable appliances or mobile objects.

The primary battery, when a 1.5V single dry battery is used, has the ability to discharge electric energy for about 10 hours with an external resistance of 5 ohms. Sufficient energy is difficult, and once it is used up, it can no longer be used, and disposal is also difficult from the viewpoint of environmental conservation.
On the other hand, the secondary battery can be regenerated any number of times by charging, but each time it is necessary to pass a current in the reverse direction between the electrodes from the outside, and there are problems such as charging cost, labor, and time loss.

For example, Japanese Unexamined Patent Application Publication No. 2005-347197 discloses a battery in which hydrogen ions and hydroxide ions are involved in a reaction at an electrode and an electromotive force is generated by an oxidation / reduction reaction.
This battery generates hydrogen ions in an acidic medium on the cathode side and generates hydroxide ions in a basic medium on the anode side, and performs an oxidation-reduction reaction in the battery. In addition to requiring an ion generation reaction field, it is necessary to supply a reactant such as hydrogen peroxide to at least one of the reaction fields in the battery.
On the other hand, among the hydrogen ions and hydroxide ions generated by the chemical reaction, a composition in which hydrogen ions are inactivated and a large amount of hydroxide ions are present is generated in advance, and this composition is used as an anode. As far as the applicant knows, the battery of the present patent application in which the electromotive force is generated is not found.

  An electromotive force composition according to the present invention is obtained by reacting a citric acid with a reaction product obtained by a primary reaction between an inorganic industrial chemical that generates hydrogen ions and hydroxide ions by reaction with an acid and an aqueous inorganic acid solution such as phosphoric acid. A secondary reaction with an organic acid aqueous solution, such as a precipitate, which is a reducing composition generated under alkalinity, is kneaded with a porous inorganic powder, thereby deactivating hydrogen ions and hydroxide ions Therefore, a composition having an electromotive force can be obtained without using electrolysis, and can be used as an anode material for a novel power cell.

The anode member of the power cell according to the present invention is a reaction product obtained by a primary reaction between an inorganic industrial chemical that generates hydrogen ions and hydroxide ions by reaction with an acid and an inorganic acid aqueous solution such as phosphoric acid, citric acid or the like. A structure in which a paste-like composition with an electromotive force obtained by secondarily reacting with an organic acid aqueous solution of the above and kneading a reducing precipitate formed under alkalinity with a porous inorganic powder is applied to a support. It has become. For this reason, of the hydrogen ions and hydroxide ions generated by the primary reaction and the secondary reaction, the protons (H ⁺ ) are adsorbed or absorbed by the porous inorganic substance in the combination of the precipitate and the porous inorganic substance. Inactivated. As a result, the anode member is in a state where an exponentially large amount of hydroxide ions are present, and an electromotive force is efficiently generated to obtain relatively large electric energy.

  In the power cell of the present invention, a sheet of paper or cloth having ion exchange ability is used between the anode member and the cathode member, and the water absorbing member is placed in a desired position in the cell between the anode member and the cathode member. Since the electric power generated by the chemical reaction is consumed and the necessary electric energy is insufficient, a small amount of water is supplied to the water absorbing member between the anode member and the cathode member. By humidifying the moisture to about 20%, the absorbed moisture is electrolyzed into hydrogen ions and hydroxide ions by energization of the anode member and the cathode member, and the hydroxide ions gather at the anode member to generate a new electromotive force. Therefore, the power source cell is self-charged without requiring an external current, and the electromotive force is self-regenerated only by supplying a small amount of water.

In addition, since it does not contain harmful substances, there is no risk of environmental pollution during disposal.

The inorganic industrial chemical used in the present invention is an inorganic industrial chemical that generates hydrogen ions and hydroxide ions by reacting with an acid among alkalis, inorganic salts, simple metals, oxides, sulfides, and carbides. Although it can be used, it is inexpensive and rich in safety during reaction. For example, zinc oxide (ZnO), calcium oxide (CaO), magnesium oxide (MgO), titanium oxide (TiO ₂ ), manganese oxide (MnO) Metal oxides such as calcium hydroxide (Ca (OH) ₂ ), alkalis such as nickel hydroxide (Ni (OH) ₃ ), carbonates such as calcium carbonate (CaCO ₃ ), or one or more Mixtures are suitable.In particular, zinc oxide, calcium carbonate, calcium oxide, magnesium oxide, titanium oxide, or a mixture of two or more types is the best because of its good workability. It is.

In the present invention, phosphoric acid, particularly orthophosphoric acid (H ₃ PO ₄ ) is preferred as the inorganic acid used for the primary reaction with the above-mentioned inorganic industrial chemicals. Further, as the organic acid used for the secondary reaction, Citric acid, acetic acid, lactic acid, and the like can be used, but citric acid (C ₆ H ₈ O ₇ ) is preferable because of good workability.

As an example of the reaction between the inorganic industrial chemicals and the acid in the present invention, for example, when powder or particles of calcium hydroxide (Ca (OH) ₂ ) are mixed in a phosphoric acid aqueous solution and subjected to a primary reaction,
Ca (OH) ₂ + H ₃ PO ₄ ―――― → CaHPO ₄ + 2H ₂ O
In this reaction process, 2 (H ⁺ + OH ⁻ ) hydrogen ions and hydroxide ions are generated.
3Ca (OH) ₂ + 2H ₃ PO ₄ ―――― → Ca ₃ PO ₄ + 6H ₂ O
During this reaction process, 6 (H ⁺ + OH ⁻ ) hydrogen ions and hydroxide ions are generated.
The reaction proceeds further----> Ca ₃ (PO ₄ ) ₂ + H ₂
Thus, a cloudy calcium hydrogen phosphate aqueous solution is produced. When this is further mixed with a citric acid aqueous solution and subjected to a secondary reaction, and adjusted to alkaline with potassium hydroxide (KOH), sodium hydroxide (NaOH), etc., hydrogen ions (H ⁺ ) and hydroxide ions (OH ⁻ ) are generated. The reduced reducing metal phosphate compound, that is, calcium hydrogen phosphate (CaHPO ₄ ) is produced as a precipitate.

In the formation process of this precipitate, first, a net-like crystal structure having cavities inside the metal particles is generated by a primary reaction of calcium hydroxide and phosphoric acid. Since the network cage crystal structure has a fine network that allows only hydrogen ions to pass therethrough and prevents hydroxide ions from passing due to the difference in size of the ions, the hydrogen ions are adsorbed and absorbed in the internal cavity.
Next, the reaction product covers the crystal structure in which the hydrogen ions have been adsorbed or absorbed by the secondary reaction with the aqueous citric acid solution, and the hydrogen ions are confined inside the cavity of the crystal structure.
When adjusted to alkalinity by adding potassium hydroxide (KOH), sodium hydroxide (NaOH), etc. to the aqueous solution after this secondary reaction, hydrogen ions are deactivated, and there are exponentially many hydroxide ions. A composition with an electromotive force is produced in the form of a precipitate.

When a porous inorganic powder such as zeolite, diatomaceous earth, or activated carbon is blended with this precipitate (calcium hydrogen phosphate and calcium phosphate), the crystal structure that adsorbs or absorbs hydrogen ions is incorporated into the porous inorganic substance. Thus, a paste-like composition having an electromotive force in which hydrogen ions (H ⁺ ) are deactivated and hydroxide ions (OH ⁻ ) are present in an exponentially large amount is obtained.

As shown in FIG. 1, the paste 4 of the composition 1 having the above electromotive force is applied to one side (both sides if necessary) of a support 2 having a desired area (4 cm × 6 cm in FIG. 1) according to the present invention. The anode member 3 of the power cell is formed.
The support 2 to which the paste 4 of the composition 1 having an electromotive force is applied may be formed to be foldable or foldable using a flexible sheet such as paper pulp, cloth, and nonwoven fabric, or a solid plate such as plastic. May be used.
The coating thickness of the paste 4 of the composition 1 having electromotive force as the anode member 3 depends on the purpose of use of the power source, the electric capacity, the support material, etc., but is usually 1 mm to 5 mm, preferably 2 mm. .

On the surface of the anode member 3 on which the composition paste 4 is applied, a cathode member 6 made of a foil or thin plate of aluminum, zinc or the like is laminated with a separator 5 interposed therebetween.
The separator 5 is a sheet having ion exchange ability. Here, the “sheet having ion exchange capability” means a sheet diaphragm such as paper pulp, cloth, and nonwoven fabric that allows electrons to pass through but does not allow other groups to pass.

  The cathode member 6 is made of aluminum foil, zinc foil or the like having a thickness of 0.1 mm to 1 mm, preferably about 0.5 mm.

Thus, by laminating the separator 5 between the application surface of the paste 4 of the composition 1 constituting the anode member 3 formed as shown in FIG. 1 and the cathode member 6, as shown in FIG. A power cell 7 of the first form is formed.
The power cell 7 is provided with electrical leads 8 and 9 such as copper and carbon provided on the anode member 3 and the cathode member 6 and connected to an electrical device such as an LED. In the cell 7, as described above, the hydrogen ions generated by the reaction of the inorganic industrial chemicals with phosphoric acid and citric acid are adsorbed and absorbed by the porous inorganic material, and are deactivated. Due to the presence of ions, it has a relatively large electromotive force.
Incidentally, the power cell 7 of the present invention is a single 4 cm × 6 cm, for example, and can obtain electric energy of 1 volt and 1 ampere.

  The more preferable second power cell 7 of the present invention is preferably provided at a desired position in the cell between the anode member 3 and the cathode member 6 of the power cell 7 configured as described above, or on the outer surface of the anode member 3, A sheet-like or layer-shaped water-absorbing member 10 having a predetermined thickness is disposed, and the water-absorbing member 10 is replenished with water to about 20% or more, so that the potential difference existing between the anode member 3 and the cathode member 6 is increased. Water supplied from the water absorbing member 10 is electrolyzed to generate hydroxide ions, and a new electromotive force is regenerated on the anode member 3 by the separator 5 having ion exchange capability.

  3 and 4 show a specific arrangement example of the water supply member 10 in the second power cell 7, and the ion exchange ability interposed between the anode member 3 and the cathode member 6 is shown. The separator 5 itself has water absorbency such as paper, cloth, nonwoven fabric, etc., and water is replenished by replenishing the separator 5 with water by the anode member 3 and the cathode member 6, and the generated hydroxide ions are the anode member. The new electromotive force is regenerated in a self-generated manner. In this specific example, since the separator 5 also serves as the water absorbing member 10, a water absorbing piece 11 protruding from the anode member and the cathode member is integrally formed on the sheet of the separator 5, and water is supplied by replenishing the water absorbing piece 11 with water. Suctioning is performed so that the separator 5 (water absorbing member 10) has a moisture content of about 20%.

  5 and 6 show other specific examples of the water absorbing member 10, and as shown in FIG. 5, the water absorbing member 10 is disposed independently between the separator 5 and the cathode member 6, as shown in FIG. The support 2, the anode member 3, the separator 5, the water absorbing member 10, and the cathode member 6 are integrally laminated to assemble the power source cell 7.

  The location of the water absorbing member 10 is not limited to the specific example shown in the figure, and the water supplied to the water absorbing member 10 as described above is electrolyzed by the anode member 3 and the cathode member 6 and is generated by the generated hydroxide ions. Any structure that self-generates electric power may be used.

The power cell 7 can be used alone, but various power sources can be used depending on the purpose of use by electrically connecting a plurality of power cells 7 in series or in parallel, or by folding a large area power cell compactly. The device can be manufactured, and can be configured into a power cell or power unit having a large capacity by assembling the power cell.

Further, when 6 cells are connected in series, 6 to 8 volts of power is generated, and the blue LED can be kept on for 200 to 800 hours. It is possible to maintain lighting for about 5,000 hours by further improving the scale and combination of the power cells to increase the power.
