Description

Description: TECHNICAL FIELD The present invention relates to an organic electrolyte battery, and more particularly, to an organic electrolyte battery using a powdered insoluble and infusible substrate having semiconductor properties as a positive electrode and a negative electrode.

(Prior Art) In recent years, electronic devices have been remarkably reduced in size, thickness, and weight, and accordingly, there has been a great demand for smaller, thinner, and lighter batteries serving as power supplies. At present, silver oxide batteries are frequently used as small and high-performance batteries, and lithium batteries have been developed and put into practical use as thinned dry batteries and small and lightweight high-performance batteries. But these batteries are 1
Because it is a secondary battery, it cannot be used for a long time by repeating charging and discharging. On the other hand, nickel cadmium batteries have been put to practical use as high performance secondary batteries,
It is still unsatisfactory in terms of weight reduction.

Although lead-acid batteries have been used in various industrial fields as large-capacity secondary batteries, the biggest disadvantage of these batteries is that they are heavy. This is fatal because lead peroxide and lead are used as electrodes. In recent years, attempts have been made to reduce the weight and improve the performance of batteries for electric vehicles, but they have not been put to practical use. However, there is a strong demand for a large-capacity and lightweight secondary battery as a storage battery.

As described above, batteries currently in practical use each have advantages and disadvantages, and are used properly according to their applications. However, there is a great need for batteries to be smaller, thinner, or lighter. As a battery that meets such needs, recently, a battery using a thin-film polyacetylene, which is an organic semiconductor, doped with an electron-donating substance or an electron-accepting substance as an electrode active material has been studied and proposed. I have. Although this battery has high performance as a secondary battery and has the potential of being thinner and lighter, it has major drawbacks. That is, polyacetylene, which is an organic semiconductor, is a very unstable substance, is easily oxidized by oxygen in the air, and is transformed by heat. Therefore, the battery must be manufactured in an inert gas atmosphere, and there is a limitation in manufacturing polyacetylene into a shape suitable for an electrode.

Further, Japanese Patent Application No. 59-24165, which is a prior application filed by the same applicant as the applicant of the present application, discloses a heat-treated product of an aromatic condensation polymer comprising carbon, hydrogen and oxygen, The atomic ratio of atoms / carbon atoms is 0.05-0.5,
In addition, the insoluble and infusible substrate having a polyacene-based skeleton structure having a specific surface area value of 600 m ² / g or more according to the BET method is used as a positive electrode and / or a negative electrode. An organic electrolyte battery characterized by using a protic organic solvent solution as an electrolyte has been proposed.

The battery is a promising secondary battery in that it has high performance, has the potential of being thin and lightweight, has high oxidation stability of the electrode active material, and is easy to mold. However, even in this prior application, there is a problem in dimensional stability at the time of heat treatment when an organic polymer material comprising an insoluble and infusible substrate having a polyacene-based skeleton structure is formed into a plate-like or cylindrical-shaped molded body without being pulverized. In addition, it is difficult to obtain a material having accurate dimensions, and there has been a problem that cracks and the like are generated during heat treatment when a large-sized molded body is to be obtained.

On the other hand, a battery electrode is generally manufactured by molding an electrode active material powder with a binder or the like because of its ease of manufacture. However, an organic electrolyte battery using a high-performance and high-strength electrode without deteriorating the performance of the insoluble infusible substrate has not been developed yet.

(Problems to be Solved by the Invention) The present inventors have found that an insoluble and infusible substrate containing a polyacene-based skeleton structure is pulverized into a powder, and a molded product of the substrate powder is used as an electrode, thereby completing the present invention. It was done.

An object of the present invention is to provide a high capacity organic electrolyte battery.

Another object of the present invention is to use an electrically conductive organic polymer powder material having the electrical conductivity of a semiconductor or a conductor, excellent physical properties, and excellent oxidation stability as an electrode active material. An organic electrolyte battery is provided.

Still another object of the present invention is to provide an organic electrolyte battery in which electrodes can be easily manufactured and which is economical.

Still other objects and advantages of the present invention will be apparent from the following description.

(Means for Solving the Problems) According to the present invention, an object and an advantage of the present invention are a heat-treated product of an aromatic condensation polymer comprising carbon, hydrogen and oxygen, which has an average particle size of 2.0 to 0.1 μm. And a powder molded body having a specific surface area value of at least 1500 m ² / g by a BET method of an insoluble infusible substrate containing a polyacene-based skeleton structure having an atomic ratio of hydrogen atom / carbon atom of 0.5 to 0.05. The present invention is also achieved by an organic electrolyte battery characterized by using, as an electrolyte, an aprotic organic solvent solution of a compound serving as a positive electrode and / or a negative electrode capable of generating ions that can be doped into an electrode by electrolysis.

The insoluble infusible substrate containing a polyacene-based skeleton structure in the present invention (hereinafter referred to as insoluble infusible substrate) is an aromatic insoluble insoluble substrate described in JP-A-59-3806 filed by the present applicant. It is obtained by subjecting the condensation polymer to heat treatment under specific conditions.

Specifically, the aromatic condensation polymer used in the present invention is (a) a condensate of an aldehyde with an aromatic hydrocarbon compound having a phenolic hydroxyl group such as phenol or formaldehyde resin, and (b) a xylene-modified phenol or formaldehyde. An aromatic hydrocarbon compound having a phenolic hydroxyl group, such as a resin (in which a part of phenol is substituted with xylene), an aromatic hydrocarbon compound having no phenolic hydroxyl group, a condensate of an aldehyde, and (c) furan Resins are preferred.

The insoluble and infusible substrate in the present invention is a heat-treated product of the aromatic condensation polymer as described above, and can be produced, for example, as follows.

An inorganic salt such as zinc chloride or sodium phosphate is mixed with the aromatic condensation polymer. Thereby, porosity can be provided to the insoluble and infusible substrate. The amount to be mixed varies depending on the type of the inorganic salt and the shape and performance of the target electrode, but is preferably 10/1 to 1/7 by weight. Also,
When obtaining a substrate that is porous and has communication holes,
It is preferable to use the inorganic salt in an amount of 2.5 to 10 times the weight of the aromatic condensation polymer. The mixture of the inorganic salt and the aromatic condensation polymer obtained in this manner is formed into a target shape such as a film, a plate, or the like, and cured at a temperature of 50 to 180 ° C. for 2 to 90 minutes for curing and molding. I do.

The cured product thus obtained is then heated in a non-oxidizing atmosphere to a temperature of 400-800C, preferably 450-750C, particularly preferably 500-700C. By this heat treatment, the aromatic condensation polymer undergoes a dehydrogenation dehydration reaction, and a polyacene skeleton structure is formed by the condensation reaction of the aromatic ring.

This reaction is a kind of thermal condensation polymerization, and the degree of reactivity is represented by the atomic ratio represented by hydrogen atoms / carbon atoms (hereinafter referred to as H / C) in the final product. The H / C value of the insoluble infusible substrate is 0.05 to 0.5, preferably 0.1 to 0.35. If the H / C value of the insoluble and infusible substrate is larger than 0.5, the polyacene-based skeletal structure is undeveloped, and the electric conductivity is undesirably low. On the other hand, when the value of H / C is smaller than 0.05, carbonization has progressed too much, and the performance as an electrode constituent material is low.

The obtained heat-treated body is sufficiently washed with water or diluted hydrochloric acid to remove the inorganic salt contained in the heat-treated body.

Thereafter, when this is dried, an insoluble and infusible substrate is obtained.

Next, the insoluble infusible substrate powder of the present invention can be obtained by pulverizing the insoluble infusible substrate. Needless to say, in order to obtain the insoluble infusible substrate powder of the present invention, the insoluble infusible substrate before pulverization has a specific surface area of 1500 m by the BET method.
^It must be at least ² / g.

The powder material of the present invention is produced by grinding the insoluble and infusible substrate. At this time, if the pores existing in the insoluble and infusible substrate are destroyed, the specific surface area is greatly reduced. Therefore, it is extremely important to powder without destroying the pores. Regarding this point, after various investigations, the impact force at the time of pulverization greatly contributes, and when Knoop hardness of the working surface to the insoluble and infusible substrate is applied and pulverization is performed by applying pulverization means of 100 or less, it is difficult to cause pore destruction. Was obtained. The pulverizing means may be appropriately selected and applied from known pulverizing means such as a ball mill, a vibration mill, a jet mill, and a kneading machine, and those having a Knoop hardness of 100 or less on the working surface with respect to the insoluble and infusible substrate as described above. Preferred results are obtained when used. As a material having a Knoop hardness of 100 or less, for example, polyethylene resin,
There are synthetic resins such as phenolic resin, polyurethane, and nylon, and it is preferable that these materials form the working surface of the crushing means. As a pulverizing means suitable for the above conditions, there is a ball mill in which all or at least the co-layer portion is formed of nylon and a ball mill in which all or at least a co-inner layer portion is formed of nylon. In the case of pulverization by the nylon ball mill, the powder can be pulverized to a target particle size with a weak impact without lowering the specific surface value of the insoluble infusible substrate, and the insoluble infusible substrate powder of the present invention can be obtained. Can be. If the material of the pulverizer has a high hardness exceeding Hk = 100, the impact force is large and the pores are crushed, and the specific surface area value is reduced. Ie
If a crusher with a low impact strength is formed by forming a working surface with a material having a low hardness of Hk = 100 or less, the crushing machine can be crushed to the particle size aimed at by the present invention without lowering the specific surface area. A favorable result is obtained. Where Knoop hardness (Hk)
Is a value (kg / mm ² ) obtained by measuring the length of the diagonal in the longitudinal direction of the indentation using a diamond indenter having a special shape such that the indentation has a diamond shape (diagonal angles of 172.5 ° and 130 °).

The insoluble infusible substrate powder of the present invention thus obtained is BET
The specific surface area by the method is at least 1500 m ² / g.

If the specific surface area of the powder is 1500 m ² / g or less, some or all of the pores are destroyed by pulverization. For example, ClO ₄ ⁻ , BF ₄ ⁻ , AsF ₅ ⁻ , (C ₂ H ₅ ) _It is difficult to smoothly and smoothly dope a dopant having a large ionic radius such as ₄ N ⁺ , and the performance of the battery, particularly the capacity, is reduced.

Further, the average particle size of the powder is 2 μm to 0.1 μm.
When the average particle size is larger than the upper limit, when the powder is molded and used as an electrode, practically sufficient strength is not obtained, and when the powder is smaller than the lower limit, it is not practical in terms of pulverization efficiency and pulverization time.

Next, the insoluble infusible substrate powder is formed into a film. At the time of film formation, it becomes easier if a conductive material and a binder are added to the insoluble and infusible substrate powder. The conductive agent is added to provide an appropriate electrical conductivity to the manufactured battery electrode.

Suitable electrical conductivity for the battery electrode is 10 ^-5 S / cm or more,
It is preferably at least 10 ⁻³ S / cm. Electric conductivity 10 ^-5 S / cm
In the following cases, the internal resistance due to the electrodes is increased, which causes a reduction in charge / discharge efficiency, which is not preferable.

The type of the conductive agent is not particularly limited, for example, activated carbon,
Carbon-based ones such as carbon black and graphite are preferred,
The smaller the particle size, the more effective. It is also possible to use a conductive polymer as the conductive material. The proportion of the conductive material varies depending on conditions such as the electric conductivity of the insoluble and infusible base powder, the type of binder, and the molding method, but is required to be 40 to 2% by weight based on the total amount.

The type of binder is a solvent that dissolves the electrolyte used when assembling the battery, for example, organic solvents such as ethylene carbonate, propylene carbonate, γ-butyrolactone, dimethylformamide, dimethylacetamide, dimethylsulfoxide, acetonitrile, dimethoxyethane, tetrahydrofuran, dioxolan, and sulfolane. There is no particular limitation as long as it is insoluble in the solvent. For example, rubber-based binders such as SBR, fluorine-based resins such as polytetrafluoroethylene, and thermoplastic resins such as polypropylene and polyethylene are preferable, and polytetrafluoroethylene is particularly preferable. The mixing ratio varies depending on the type, but is preferably 20% by weight or less based on the total amount. If the mixing ratio exceeds 20% by weight, the electrolyte cannot sufficiently enter the inside of the electrode, and the capacity is undesirably reduced.

The powder of the insoluble and infusible substrate, the conductive material, and the binder as described above are sufficiently kneaded and molded to form an electrode.

The organic electrolyte battery of the present invention has a specific surface area value of at least 1500 m ² / g by the BET method prepared by the above-described method, an average particle size of 2.0 to 0.1 μm, and an atomic ratio of hydrogen atom / carbon atom. An aprotic organic solvent solution of a compound capable of forming a dopable ion in the electrode by electrolysis as a positive electrode and / or a negative electrode using an insoluble infusible substrate powder compact containing a polyacene-based skeleton structure of 0.5 to 0.05; Is an electrolyte.

Compounds that can be used in the electrolyte and generate ions that can be doped into the electrode include alkali metal or tetraalkylammonium halides, perchlorates, hexafluorophosphate, hexafluoroarsenate, and tetrafluoride. Formates and the like, specifically, LiI, NaI, NH ₄ I, LiClO ₄ , LiAsF ₆ , LiBF ₄ , KPF
₆ , NaPF ₆ , R ₄ NClO ₄ , R ₄ NAsF ₆ , R ₄ NPF ₆ , R ₄ BF ₄ (R represents the same or different alkyl group).

Examples of the aprotic organic solvent for dissolving the compound include ethylene carbonate, propylene carbonate,
γ-butyrolactone, dimethylformamide, dimethylacetamide, dimethylsulfoxide, acetonitrile, dimethoxyethane, tetrahydrofuran, methylene chloride, and mixtures thereof. Selection should be made in consideration of the solubility of the compound used as an electrolyte, battery performance, and the like. is important.

Most preferably, the concentration of the compound in the electrolytic solution is at least 0.1 mol / or more in order to reduce the internal resistance due to the electrolytic solution, and usually a range of 0.2 to 1.5 mol / is preferable.

The battery of the present invention uses a powdered insoluble and infusible substrate having a polyacene skeleton structure as a positive electrode and / or a negative electrode, and uses an electrolyte obtained by dissolving a doping agent in an aprotic organic solvent. The function utilizes electrochemical doping and electrochemical undoping of a doping agent into an insoluble infusible substrate powder used as an electrode. That is, energy is stored by electrochemical doping of the insoluble infusible substrate powder with the doping agent, or is released to the outside and is extracted as electrical energy by electrochemical undoping, or internally. It is stored.

The batteries according to the present invention are divided into two types. First
The type is a battery using an insoluble and infusible substrate powder molded body of both the positive electrode and the negative electrode. The second type uses an insoluble and infusible substrate powder molded body for the positive electrode, and the negative electrode is made of an alkali metal or an alloy thereof. This is a battery using electrodes. Specific examples of the alkali metal to be applied include, for example, cesium, rubidium, potassium, sodium, lithium and the like, and among these, lithium is most preferable.

The shape and size of the electrode composed of the powdered insoluble and infusible substrate disposed in the battery may be appropriately selected depending on the intended battery, but the battery reaction is an electrochemical reaction on the electrode surface. Therefore, it is advantageous to increase the surface area of the electrode as much as possible. Further, as the current collector for extracting a current from the insoluble infusible substrate powder to the outside of the battery, the insoluble infusible substrate powder or the insoluble infusible substrate powder doped with a doping agent may be used. However, other conductive substances having corrosion resistance to the doping agent and the electrolytic solution, such as carbon, platinum, nickel, and stainless steel, can also be used.

Next, an example of an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is an explanatory view of a battery according to the present invention. In the figure, (1) positive electrode, (2) negative electrode, (3) current collector, (4)
Denotes an electrolytic solution, (5) denotes a separator, (6) denotes a battery case, and (7) denotes an external terminal.

First, a first type of battery according to the present invention, that is, a battery using an insoluble and infusible substrate powder molded body for both positive and negative electrodes will be described. The positive electrode (1) is a film-shaped or plate-shaped insoluble infusible substrate powder molded body, which may be doped with a doping agent or may be undoped. The negative electrode (2) is an insoluble and infusible substrate powder molded body having a shape such as a film shape or a plate shape, and may be doped with a doping agent or undoped. After assembling the battery, a voltage is applied from an external power supply to dope the doping agent. For example, when the undoped insoluble infusible substrate powder molded body is used for both electrodes, the electromotive voltage of the battery after assembling the battery is OV, and a voltage is applied from an external power supply to dope a doping agent to both electrodes. The battery will have an electromotive force. The current collector (3) extracts current from each electrode to the outside, or supplies current for electrochemical doping, that is, charging,
The electrodes and the external terminal (7) are connected so as not to cause a voltage drop by the method described above. The electrolyte (4)
The compound capable of forming ions capable of doping an aprotic organic solvent into both positive and negative electrodes is dissolved. The electrolyte is usually in a liquid state, but may be used in a gel or solid state to prevent leakage. Separator (5)
Is arranged for the purpose of preventing contact between the positive and negative electrodes and holding the electrolyte, and has continuous pores that are durable to the electrode active material such as an electrolyte, a doping agent, and an alkali metal. Porosity is preferred, and cloths, nonwoven fabrics, porous bodies, and the like made of glass fiber, polyethylene, polypropylene, or the like are usually used. The thickness of the separator is preferably thin in order to reduce the internal resistance of the battery, but is determined in consideration of the amount of retained electrolyte, flowability, strength, and the like. Both the positive and negative electrodes and the separator are the battery case (6)
Is set so as not to cause a practical problem. The shape, size, and the like of the electrode may be appropriately determined depending on the shape and performance of the intended battery. For example, in order to manufacture a thin battery, the electrode is preferably in the form of a film. In order to manufacture a large-capacity battery, it can be achieved by laminating a large number of film and plate-like electrodes alternately on both positive and negative electrodes.

Next, the second type of the battery according to the present invention, that is, using the insoluble and infusible substrate powder molded body for the positive electrode (1) and the negative electrode (2)
The case where an alkali, a metal, or an alloy thereof is used for the above will be described. The positive electrode (1) in FIG. 1 is an insoluble and infusible substrate powder molded body, and the negative electrode (2) is an alkali metal or an alloy thereof. And in the case of this second type, the do pink mechanism,
That is, the operation mechanism of the battery is further roughly classified into the following two. The first is a battery provided with a mechanism in which doping of an insoluble infusible substrate with an electron-accepting doping agent corresponds to charging and undoping thereof corresponds to discharging. For example, when an undoped insoluble infusible base powder molded body is used as an electrode and LiClO ₄ 1 mol / propylene carbonate solution is used as an electrolyte for lithium, the starting force after assembling the battery is
2.5-3.0V. Next, apply a voltage from an external power supply to
When the lO ₄ ions doped into the insoluble and infusible substrate, the electromotive force becomes 3.5～4.5V. The second is a battery having a mechanism in which doping an insoluble infusible substrate powder with an electron-donating doping agent corresponds to discharging, and undoping corresponds to charging. For example, in the above-described battery configuration, the electromotive voltage after battery assembly is 2.5 to 3.0 V, and the starting force becomes 1.0 to 2.5 V when lithium ions are doped into the insoluble and infusible substrate by discharging current to the outside. When a voltage is applied from an external power supply and lithium ions are undoped, the electromotive force becomes 2.5 to 3.0 V again.

The doping or undoping may be performed under a constant current, a constant voltage, or under a condition where the current and the voltage change, but the amount of the doping agent doped into the insoluble infusible substrate powder may be The number of ions to be doped with respect to one carbon atom of the fusible substrate is preferably 0.5 to 20% in terms of percentage.
