GEL ELECTROLYTE

摘要

A gel electrolyte prepared by impregnating a composition comprising 100 parts by weight of a cross-linked polyalkylene oxide, prepared by the reaction between a polyalkylene oxide having a weight-average molecular weight of 1,000 to 1,000,000 and an isocyanate, and 0.1-20 parts by weight of an inorganic oxide with a solution of an inorganic electrolyte in a nonaqueous organic solvent. It is excellent in ionic conductivity and mechanical strengths and useful as the material of cells and electrochemical devices.
