ELECTROLYTE FOR ELECTRIC DOUBLE-LAYER CAPACITOR AND ELECTRIC DOUBLE LAYER CAPACITOR

摘要

PROBLEM TO BE SOLVED: To provide the electrolyte for electric double-layer capacitor which shows a low coefficient of viscosity and excellent conductivity and moreover may be used even at low temperatures. SOLUTION: In the electrolyte for electric double-layer capacitor, tetrafluoro-boric-acid-spiro(1,1')-bipiro-ridium are included as the electrolyte in the mixed solvent of dimethyl-carbonate and propylene-carbonate, and the electric double-layer capacitor uses the above electrolyte.
