Description

[Detailed description of the invention]

The present invention relates to a non-aqueous secondary battery that has a long cycle life and good charge/discharge efficiency (Coulombic efficiency).

[So-called polymer batteries, which use polymer compounds with conjugated double bonds in their main chains as electrodes, are expected to be used as high-energy-density secondary batteries. Many reports have already been made regarding polymer batteries, for example, B. G. Nigley et al., Journal of the Chemical Society, Chemical Communication, 1979.

In addition, there has already been a proposal to use polyaniline, which is obtained by oxidative polymerization of aniline, which is a part of conjugated polymers, as the 'd3 electrode of aqueous or non-aqueous batteries [A.G. et al., Polymer Preblinz, Volume 25, Number 2.

). However, in polymer batteries using conventionally known polymers for the N electrode, it has been difficult to achieve high charge/discharge efficiency and a long cycle life. Therefore, an object of the present invention is to solve the above-mentioned drawbacks of the conventional polymer batteries using polymers for electrodes, and to provide a non-aqueous secondary battery with a long cycle life and good charge/discharge efficiency. . 1) As a result of various studies on electrode materials, the present inventors have determined that a molded product made of a composition consisting of an aniline polymer, an aqueous dispersion of a fluororesin, and a low-boiling water-soluble organic compound can be used as a positive electrode. It has been discovered that by using the above-mentioned method, a non-aqueous secondary battery that effectively achieves the above object can be obtained, leading to the present invention. That is, according to the present invention, in a nonaqueous secondary battery having a positive electrode, a negative electrode, and a nonaqueous electrolyte as main components, the positive electrode can be made of an aniline polymer, an aqueous ice version of a fluororesin, and a low-boiling water-soluble organic compound. Provided is a non-aqueous secondary battery characterized by using a molded article formed from a composition. The aniline polymer used to produce the positive electrode in the present invention can be obtained by oxidative polymerization or oxidative copolymerization of an aniline compound represented by the following general formula. 3R4 [However, in the formula, R1 to R6 may be the same or different, and include halogen, hydrogen atom, amino group, nitro group, allyl group, alkyl group having 10 or less carbon atoms, alkoxy group having 10 or less carbon atoms, carbon Indicates an aryl group having a number of 6 to 10. ] Specific examples of the aniline compound represented by the above general formula include aniline, 2-methoxyaniline, 3-methoxyaniline, 2,3-dimethoxyaniline, 2.5-dimethoxyaniline, 3.5-dimethoxyaniline, 2 -Ethoxy-3-methoxyaniline, 2,5-Schiff L-niline, 2-phenyl-3-methylaniline, 2,3.
5-trimethoxyaniline, 2,3-dimethylaniline, 2.3,5.6-titramethylaniline, 2-methylaniline, 2-aminoaniline, 2-nitroaniline,
Examples include N-methylaniline, diphenylamine, N,N-dimethylaniline, triphenylamine, etc.
It is not necessarily limited to these. Aniline polymers can be produced by either electrochemical polymerization or chemical polymerization. When electrochemical polymerization is used, the aniline compound is polymerized by anodic oxidation. For this purpose, a current density of 2 to 20 mΔ/α2 is used, for example. Most are 1
A voltage between 0 and 300 volts is applied. The polymerization is preferably carried out in the presence of an auxiliary liquid in which the aniline compound is soluble. For this purpose water or polar organic solvents can be used. When using a water-miscible solvent, a small amount of water may be added. Suitable organic solvents are, but are not necessarily limited to, alcohols, ethers such as dioxane or tetrahydrofuran, acetone or acetonitrile, benzonitrile, dimethylformamide or N-methylpyrrolidone. Polymerization is carried out in the presence of a complexing agent. This includes BFii, ASFi, and ASFii as anions. Sb Fi, Sb C! J-, PFi, CJ Oi. It means a salt containing H8Oi and 5o42- groups. These salts contain as cations, for example H+, quaternary ammonium cations, lithium, sodium or potassium. The use of compounds of this type is known and is not the subject of the present invention. In these compounds, the aniline polymer usually contains 20 to 100% of the anionic complexing agent.
It is used in an amount containing mol%. When producing aniline polymers by chemical methods, for example, aniline compounds can be polymerized in aqueous solution with strong acids or with inorganic peroxides such as potassium perylllate. Since a salt is present in these methods, the aniline polymer becomes a complex compound with the corresponding anion. The aniline polymer obtained by converting it into a compound with an anion may be used as a positive electrode material as it is, or it may be used as a positive electrode material after the complexed anion is chemically or electrochemically removed. When using an aniline polymer as a positive electrode material, other GW materials such as carbon black, metal powder, metal fibers, carbon fibers, etc. may be mixed therein. In addition, the aqueous dispersion of fluororesin used to produce the positive electrode in the present invention is, for example, poly-
4-Fluoroethylene, polychlorotrifluoroethylene, polyvinylidene fluoride, polyvinyl fluoride, 4
- Fluorinated ethylene and 6-- 7 = Fluororesins such as a copolymer of fluorinated propylene, a copolymer of 4-fluorinated ethylene and ethylene, etc., are each in the form of an aqueous dispersion. Although the concentration of fluororesin in the aqueous dispersion is not particularly limited, generally an aqueous ice version with a fluororesin concentration of 20 to 70% by weight is used. Two or more types of aqueous fluororesin dispersions may be used in combination. The mixing ratio of the aniline polymer and the fluororesin aqueous dispersion is 1 to 100 parts by weight of the fluororesin aqueous dispersion in terms of solid content.
The amount is 30 parts by weight, preferably 4 to 15 parts by weight. If the mixing ratio of the aqueous fluororesin dispersion is less than 1 part by weight in terms of solid content, moldability is poor and the resulting electrode has poor flexibility. On the other hand, if the mixing ratio of the aqueous fluororesin dispersion is more than 30 solids, the original properties of the aniline polymer will be impaired, which is not preferable. -Q- Furthermore, the low boiling point water-soluble organic compound used to produce the positive electrode in the present invention means a water-soluble organic solvent with a boiling point of 160°C or less, and representative examples include acetone, methane, etc. alcohol, ethyl alcohol, allyl alcohol,
n-propyl alcohol, iso-propyl alcohol,
Examples include methyl ethyl ketone and methyl acetate. Two or more of these low-boiling water-soluble organic compounds may be used in combination. If a water-soluble organic compound having a high boiling point, for example, a boiling point higher than 160° C. is used, high heat is required to remove the organic compound, which may result in deterioration of the aniline polymer, so it is preferable to use <Z stomach. Further, when a water-insoluble organic compound is used, it is not preferable because the water-based ice version of the aniline polymer or fluororesin is difficult to disperse. The mixing ratio of the low-boiling water-soluble organic compound is 0.5 to 100 parts by weight, preferably 5 to 30 parts by weight, based on 100 parts by weight of the aniline polymer. If the mixing ratio of the low-boiling point water-soluble organic compound is less than 0.5 mm part, the flexibility of the electrode obtained will not be sufficient, and on the contrary, if the mixing ratio of the low-boiling point water-soluble organic compound is more than 100 parts by weight. This is not preferable since it becomes difficult to remove low-boiling water-soluble organic compounds. The aniline polymer composition according to the present invention can be prepared by simultaneously mixing and stirring the three components of the aniline polymer, an aqueous fluororesin dispersion, and a low-boiling water-soluble organic compound. In order to obtain an aniline polymer composition, an aqueous dispersion of an aniline polymer and a fluororesin are mixed in advance, a low boiling point water-soluble organic compound is added to this mixture, and the mixture is stirred to uniformly mix. It is preferable. For mixing, known stirring methods or other methods can be used, and the mixing time varies depending on the type of aniline polymer, aqueous dispersion of fluororesin, and low-boiling water-soluble organic solvent used, so it cannot be generalized. I can't decide, but
Generally within the range of several minutes to several hours. The aniline polymer composition obtained by thorough mixing can be molded into electrodes having various shapes by applying pressure. The temperature during molding is between room temperature and 160° C., and the pressure to be applied cannot be determined simply because it changes depending on the intended V-shape and density of the electrode. Further, the molding may be performed under reduced pressure. Most of the water and low-boiling water-soluble organic compounds contained in the aniline polymer composition evaporate during molding of the aniline polymer composition, but are completely removed by drying the molded product. The aniline polymer electrode thus obtained is used as the positive electrode of the non-aqueous secondary battery of the present invention. The negative electrode used in the non-aqueous secondary battery of the present invention is not particularly limited, and examples thereof include bolivyl and polypyrrole derivatives,
Polythiophene and polythiophene derivatives, conductive polymers such as polyquinoline, polyacene, polyparaphenylene, and polyacetylene, intercalation compounds such as graphite and Ti82, alkali metals or their alloys such as lithium, sodium, and lithium aluminum, and alkali metals or their alloys. Examples include composites of alloys and conductive polymers, among which preferred are polyacetylene, polyparaphenylene, lithium-aluminum alloys, and composites, particularly preferred are lithium-aluminum alloys. , and complexes.

Shinichiren-1 Hereinafter, the present invention will be explained in more detail by giving Examples and Comparative Examples. Example 1 [Preparation of positive electrode] 500 ml of 1N aqueous hydrochloric acid solution was placed in 11 three-necked flasks equipped with a stirrer. , 20 g (0.22 mol) of aniline were added thereto, and 66.7 g (0.29 mol) of ammonium persulfate was added with sufficient stirring at a temperature of 40° C., followed by polymerization for 4 hours.

Immediately, polymerization occurred on the surface of the catalyst solution, producing a film-like acetylene high polymer.
