Abstract

The present invention relates to the method of increasing the working voltage of electrical double layer capacitor with enhanced working voltage, which has electrodes fabricated from porous carbon powder in which the pore sizes and the specific surface are created by extracting the non-carbon atoms from the carbon-rich organic or mineral compounds. The method is performed by step-by-step treatment of supercapacitor with the conditioning voltage (Uc), which is increased gradually up to the working voltage (Uw) by the voltage step (DUc) which is less or equal to 0.2V.
