Abstract
An electrochemical capacitor is provided having double-layer electrode elements interposed with a separator. The electrode elements being made of activated carbon and impregnated with a nonaqueous electrolytic liquid yields a capacitor with low internal resistance, greater capacitance and higher energy density. Methods for producing the activated carbon electrodes and the capacitor assembly are also described.
