Abstract

The development of the electric double-layer capacitor with ultra-high capacitance and extremely low DC resistance is described. The capacitance ranges from 1 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 on aluminum foil collector electrodes, a separator, and an organic electrolyte. Details of the electrical characteristics and 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 also discussed
