NON-WATER ELECTROLYTE ELECTRIC DOUBLE-LAYER CAPACITOR, ELECTRODE STABILIZING AGENT THEREFOR, AND NON-WATER ELECTROLYTE FOR ELECTRIC DOUBLE-LAYER CAPACITORS

摘要

PPROBLEM TO BE SOLVED: To provide an electrode stabilizing agent for non-water electrolyte electric double-layer capacitors that can decrease the leak current of the electric double-layer capacitor. PSOLUTION: This electrode stabilizing agent provides for non-water electrolyte electric double-layer capacitors. It consists of phosphagen compounds with a group containing any atom double bond except phosphorus-nitrogen double bond in a molecular structure. A carbon-carbon double bond is desirable as a double bond except the above phosphorus-nitrogen double bond, and an aryl group or a vinyl group is especially desirable as a group containing a carbon-carbon double bond.
