PROBLEM TO BE SOLVED: To provide a polymer solid electrolyte material with high ionic conductivity, high working capability, high softness, and high mechanical strength, and a battery using this material by forming the polymer solid electrolyte with a specific weight parts of a specific copolymer, an electrolyte, and a plasticizer. SOLUTION: A copolymer of (a) component of a polymer solid electrolyte contains at least one kind of a monomer unit comprising trifluorovinylether represented by formula (in the formula, X is a perfluoroalkyl group having 1-18 carbon atoms, the end of the carbon chain may be hydrogenated, and an ether group may be contained in the chain.), and a monomer unit comprising vinylidene fluoride. As an electrolyte of (b) component, inorganic acids, organic acids, and salts of them are listed. As the plasticizer of (c) component, ethylene carbonate or the like is listed. (a) and (c) components are 5-90 pts.wt., and (b) component is 1-90 pts.wt. based on 100 pts.wt. of the sum of (a), (b), and (c) components. |
