Abstract

The authors describe the development of an electric double-layer capacitor with ultra-high capacitance and extremely low DC resistance. The capacitance ranges from 1 F to 500 F and the DC resistance is less than one-fifth of that of the conventional capacitor with organic electrolytes. The capacitor consists of an activated carbon layer newly developed on aluminum foil collector electrodes, a separator, and an organic electrolyte. Details of the electrical characteristics and the reliability of the capacitors are presented. Several features of activated carbon electrodes and the mechanism for the improvement of the DC resistance are discussed. Some examples of the potential application of the capacitor for high-current-load uses are discussed
