Verfahren zum Herstellen einer polarisierten Elektrode für einen elektrischen Doppelschichtkondensator.

摘要

A pressure ranging from 50 Kgf/cm<2> to 800 Kgf/cm<2> is applied to a powder of fine particles of activated carbon (1,2,3), and while the pressure is being applied to the particles, pulse voltages are applied between the particles for producing electric discharges between the particles, and the particles are kept at a temperature ranging from 700 DEG C to 1000 DEG C, thereby sintering the fine particles of activated carbon to form an electrode of a porous sintered body. Two such electrodes (32) are impregnated with an electrolyte to produce polarized electrodes, and a separator (33) is sandwiched between the polarized electrodes, thus forming an electric double layer capacitor.
