Therefore, various studies have been conducted on solid electrolytes that can solve the problems of moldability and film formation. For example, an organic polymer electrolyte of polyethylene oxide (PIEO), an organic polymer electrolyte containing a polyethylene oxide part and a polypropylene oxide part of a polyfunctional polyether molecular structure in a random copolymerization type (Japanese Patent Application Laid-Open No. 1983-1989-1)

The polymerization-reactive functional groups include alkenyl groups such as vinyl groups, groups with unsaturated bonds such as acryloyl groups and methacryloyl groups, and linear and cyclic moieties such as those containing Si.

Further, as the negative electrode active material, alloys such as lithium metal, lithium aluminum, lithium-lead, lithium-based alloy, lithium-aluminum-tin, and wood alloy, or those used as the above-mentioned positive electrode active materials can also be used.

The positive electrode of a lithium battery is generally made of a sheet formed by bonding the above-mentioned active materials with a solid electrolyte. It can be mixed into the positive electrode to improve electron conduction. When producing a positive electrode sheet as described above, several types of dispersion medium and dispersant may be added to obtain a uniform mixed dispersion system. Other methods for manufacturing the positive electrode include thin film forming methods such as CVD, M deposition, sputtering, and aerosol deposition, and methods that use substances other than solid electrolytes as a binder (for example, borotetrafluoroethylene, etc.). Even in this case, it is possible to use a solid electrolyte in combination.

On the other hand, pure lithium or a lithium alloy sheet is often used for the negative electrode, but a method similar to the above method for manufacturing the positive electrode can also be used.

The separator can also be formed by forming a solid electrolyte alone into a sheet and disposing it between the positive electrode and the negative electrode, or by applying a solid electrolyte composition solution to the positive electrode or the negative electrode to form a composite. Furthermore, as other separator materials, porous bodies such as polypropylene nonwoven fabrics and microporous polyolefin membranes can also be used.

In this case, a liquid electrolyte or a solid electrolyte may be present in the porous body. As a method for compounding, it is also possible to apply a positive electrode or negative electrode composition liquid to a solid electrolyte sheet or a porous body, and the method is not particularly limited.

Note that although the present invention is characterized by the use of an organic solid electrolyte, an inorganic solid electrolyte may also be used for Inno1 U7.

Function: Since the present invention uses an organic polymer consisting of 1,000 polymers having a specific structure, the organic polymer structure becomes amorphous, and since it has side chains similar to the main chain, the crystallization temperature of the organic polymer is lowered. When an ionic compound such as a lithium salt is included, it facilitates the movement of lithium ions, and as a result, the lithium ion conductivity in the temperature range below room temperature is -1-L, excellent in low-temperature properties, and stable in quality. It is possible to obtain a battery that is Furthermore, since the organic polymer is thermosetting, it can take on a variety of shapes and can be made into a film with excellent adhesion to the electrode surface, making it possible to obtain a variety of practical batteries.
