HIGH POLYMER SOLID ELECTROLYTE

摘要

PURPOSE:To obtain high polymer solid electrolyte which is excellent in ion conductivity and is chemically and electrochemically stable by incorporating ionic salt in a high polymer compound which is formed in a manner wherein the epoxy radical of a compound having an epoxy radical is subjected to cation- ring-opening-polymerization. CONSTITUTION:A high polymer compound which is formed in a manner wherein an epoxy radical of a compound having the epoxy radical is subjected to cation- ring-opening-polymerization contains ionic salt. The high polymer compound is further preferably constituted of a high polymer compound which has two or more epoxy radicals as well as which is mesh-like by the polymerization. Thus as the high polymer electrolyte which was formed in a manner wherein the epoxy radical of the compound having the epoxy radical is cation-ring- opening-polymerized is high polymer solid electrolyte containing ionic salt, the high polymer solid electrolyte which is excellent in ion conductivity and is chemically and electrochemically stable can be obtained.
