Title:
ELECTROLYTE SHEET
Document Type and Number:
Japanese Patent JP3143273
Kind Code:
B2
Abstract:
PURPOSE: To provide an electrolyte sheet formable to a thin and large-area sheet, having excellent conductivity and usable as an electrochemical element such as battery, electric double layer capacitor, etc.
CONSTITUTION: This electrolyte sheet is composed of a copolymer of acrylonitrile and methyl acrylate, methyl methacrylate or vinyl acetate, an aprotic solvent solution of a salt and powder of electrically insulating inorganic substance containing alumina or silica. The electrically insulating inorganic substance powder containing alumina or silica acts as cross-linking points in a gelatinous substance formed by the copolymer and the aprotic solvent containing a salt as a solute to give an electrolyte sheet having excellent shape-retaining property and high mechanical strength without lowering the conductivity.
