ELECTRIC DOUBLE LAYERED CAPACITOR

摘要

PURPOSE:To provide an electric double layered capacitor with a high breakdown voltage and high energy density per unit volume of a cell. CONSTITUTION:The solvent of electrolyte of an electric double layered capacitor contains maleic anhydride and/or its derivative. Preferably, the solvent of the electrolyte is composed of mixed solvent of maleic anhydride and/or its derivative and chain carbonate and/or cyclic carbonate.
