These features meet the demands for various electronic components that are small, lightweight, and highly reliable as electronics advances, and research and development efforts are therefore being actively conducted.

That is, polymers such as polyethylene oxide, polypropylene oxide, polyethyleneimine, polyepichlorohydrin, polyethylene succinate, Li,
Solid electrolyte compositions comprising a combination of Na and inorganic ion salts and batteries using these compositions have already been proposed (eg, JP-A-55-98480).

、これらの例においても、イオン伝導度が不充分であり
、実用化までには至っていない。In order to increase ionic conductivity, polyethylene glycol and other cross-linking agents have recently been used in solid electrolytes using polymer materials, from the perspective that the presence of an amorphous region of the polymer is a major factor in providing high ionic conductivity. A method of crosslinking has been proposed by
No. 48003, No. 60-262852, etc.), and
There is also a report of crosslinking trifunctional polyoxyalkylene glycerin using an aromatic diisocyanate as a crosslinking agent (1985 Chemical Society of Japan Spring Annual Meeting 3Z-46)
Even in these examples, the ionic conductivity is insufficient, and they have not been put into practical use.

イオン伝導が促進されるためである。When using a polymer material as a solid electrolyte, the glass transition point of the solid polymer electrolyte used is important as a physical property that contributes to electrical conductivity. That is, the lower the glass transition point of a substance, the more active the micro-Brownian motion of the polymer chain becomes, promoting ionic conduction.
