Kondensator mit Elektrolyt, der ein Gemisch von Dinitrilen enthält

摘要

An electrical capacitor comprises a pair of electrodes separated by an electrolyte which comprises a salt and a solvent contg. succinonitrile mixed with a second dinitrile to form a liq. at room temp. Also claimed are: (a) the above capacitor in which at least one of the electrodes has an oxide layer; and (b) an electrochemical double layer capacitor in which at least one of the electrodes comprises a material selected from carbon foams, carbon fibres, carbon composites, metal filled composites, metals, and conductive metal oxides.
