Electrochemical capacitor

摘要

The invention relates to an electrochemical capacitor with electrodes of activated carbon. Such a capacitor is to be improved in the sense that the electrodes are mechanically stable and also exhibit a large capacity per unit of area. To this end, the invention provides electrodes which consist of glass carbon activated in concentrated sulfuric acid at temperatures of up to about 330 DEG C. The electrochemical capacitor according to the invention is suitable for use in electric circuits.
