ELECTROLYTE FOR ELECTROCHEMICAL CAPACITOR AND ELECTROCHEMICAL CAPACITOR USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an electrolyte that can improve its solubility to a solvent at very low temperature, suppress a quantity of acid corroding a collector and prevent the aging degradation of performance of a capacitor. SOLUTION: The electrolyte for electrochemical capacitor contains a compound represented by a general formula (1), where B is boron atom; X1and X2are O or S independently, respectively; Q is bivalent C1-C3 hydrocarbon group or bivalent C1-C3 halogenated hydrocarbon group; G is halogen atom; monovalent C1-C10 hydrocarbon group, monovalent C1-C10 halogenated hydrocarbon group, or X3G3(X3: O or S; G3: monovalent C1-C10 hydrocarbon group or monovalent C1-C10 halogenated hydrocarbon group); m is one or two; n is zero or two.
