ABSTRACT:
A process for producing a polymer electrolyte for a nonaqueous battery by mixing a vinylidene fluoride copolymer and a nonaqueous electrolytic solution with a solvent that can be evaporated, wherein the vinylidene fluoride copolymer comprises 80 to 97 wt. % of vinylidene fluoride monomer units and 3 to 20 wt % of units of at least one monomer copolymerizable with vinylidene fluoride monomer and has an inherent viscosity of 1.5 to 10 dl/g, and evaporating the solvent to form a polymer electrolyte comprising the vinylidene fluoride copolymer impregnated with the nonaqueous electrolytic solution.
