To obtain a high-durability polymer electrolyte which controls an attack by a peroxide free radical, has higher durability than that of a conventional hydrocarbon-based electrolyte and a low cost and to provide a method for producing the same.
The high-durability polymer electrolyte is provided with a fluorocarbon skeleton converted from a hydrocarbon skeleton. The method for producing the high-durability polymer electrolyte comprises a first fluorination process for converting a part or the whole of the hydrocarbon skeleton constituting a solid polymer electrolyte to the fluorocarbon skeleton. In this case, the method is provided with a non-protonizing process for converting the electrolytic group of the solid polymer electrolyte to a halide group or a metal salt before the first fluorination process and with a protonizing process for converting the halide group or the metal salt to the electrolytic group after the fluorination process.
