ELECTROLYTE SOLUTION FOR DOUBLE LAYERED CAPACITORS AND DOUBLE LAYERED CAPACITOR CONTAINING SAID ELECTROLYTE SOLUTION

摘要

The present invention relates to a double-layer storage capacitor electrolyte solution comprising one or more conductive salts comprising cations having an additional substituent is not the same on both the maximum diameter 9.20 Å and the central atom. In addition, the electrolyte solution comprises at least one functional group selected from a solution containing a lactone and a nitrile. Electrolyte solution of the present invention when selecting a solvent of acetonitrile compared to the ordinary electrolytic solution shows a high aspect at a low temperature, and thus the double-layer capacitor electrolytic solution according to the present invention has provided an improved electrical characteristic at a low temperature. ; Capacitors, electrolyte, bilayer, acetonitrile, cationic
