MOLDING MATERIAL FOR HIGH-MOLECULAR SOLID ELECTROLYTES, MOLDINGS OF HIGH-MOLECULAR SOLID ELECTROLYTES AND PROCESS FOR PRODUCTION THREOF, AND POLYETHER POLYMER AND PROCESS FOR PRODUCTION THEREOF

摘要

A molding material for high-molecular solid electrolytes, consisting of a polyether polymer having a water content of 400 to 5,000 ppm by weight; moldings of high-molecular solid electrolytes which are produced by mixing the molding material with an electrolyte salt soluble in the polyether polymer and molding the resulting mixture and which are excellent in ionic conductivity and mechanical strengths; and a polyether polymer having a water content of 0.04 wt% or below and a toluene- insoluble content of 5 wt% or below, which can give moldings of high-molecular solid electrolytes having smooth surfaces.
