Abstract
A solid polymer electrolyte having improved ionic conductivity and adhesion with an electroconductive substrate and also remarkably enhanced heat resistance is formed with a vinylidene fluoride copolymer which contains 50-97 mol. % of vinylidene fluoride monomer and 0.1-5 mol. % of an unsaturated dibasic acid monoester or an epoxy group-containing vinyl monomer and further has been crosslinked, thereby improving the performances of a non-aqueous battery, such as a lithium ion battery.
