COMPOSITE ELECTROLYTE, AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a composite electrolyte suppressing elution and swell of the electrolyte, high in electric conductivity, and excelling in chemical durability, and also to provide its manufacturing method.

SOLUTION: This composite electrolyte manufacturing method comprises: a modification process of introducing a reactive functional group A comprising a sulfonamide group or its derivative, or a sulfonyl halide group or its derivative into a surface of a hydrocarbon-based porous base material; and a compounding process of filling an electrolyte monomer and/or an electrolyte polymer having a reactive functional group B producing a sulfonimide group by reacting with the reactive functional group A in the hydrocarbon-based porous base material to react the reactive functional group A with the reactive functional group B. This composite electrolyte is provided by such a method.
