Verfahren zum Herstellen einer polarisierten Elektrode für einen elektrischen Doppelschichtkondensator.

摘要

At least two powders of minute active carbon particles (S,L) having different diameters are mixed, and the mixture is placed in a mould (10). While a pressure is being applied to the mixture in the mould, pulse voltages are applied between the minute active carbon particles for producing electric discharges therebetween, and the minute active carbon particles are kept at a predetermined temperature, thereby sintering the minute active carbon particles into a porous sintered body, which is used as an electrode. Two such electrodes are impregnated with an electrolyte, to produce a pair of polarized electrodes which are sandwiched between current collectors (50), and separated by a separator (40).
