HEAT RESISTANT HIGH POLYMER ELECTROLYTE GEL AND ITS MANUFACTURE

摘要

PROBLEM TO BE SOLVED: To provide a high polymer electrolyte gel which has a high ion conductivity, maintains the form of a solid even in a high temperature, generates no mutual separation between a liquid component and a solid component, furnishes an elasticity to contact closely with an electrode and a strength to bear to the molding process, and can be formed in various forms at an adequate thickness. SOLUTION: In this gel, 89wt.% to 98wt.% of acrylonitrile is included in an acrylonitrile system polymer, or to an acrylonitrile polymer including at least one sort of electrolyte and a solvent, and it satisfies the formula: 104000-(A×1000)<=B<=1490000-(A×10000) (in the formula, A: acrylonitrile including amount (wt.%), and B: weight mean molecular weight of the acrylonitrile polymer). Furthermore, the ion conductivity more than 10<-3> S/cm at 20 deg.C is given, and 'configulation retention' is indicated in a heat resistant test, and the acrylonitrile polymer is included at the ratio from 3wt.% to 9wt.%.
