Abstract: PROBLEM TO BE SOLVED: To provide a polymer electrolyte containing a copolymer of vinylidene fluoride and hexafluoropropylene and a titania nanoparticle, and to provide its manufacturing method. SOLUTION: The polymer electrolyte is produced by lysing the copolymer of vinylidene fluoride and hexafluoropropylene and the nanometer-sized titania grain into a solvent, and then manufacturing a porous polymer membrane to be impregnated in an electrolytic solution.
