Title: THE EFFECT OF AMOUNT OF ACTIVATING AGENT ON THE CAPACITANCE CHARACTERISTICS OF ANTHRACITE-BASED HIGH SURFACE AREA ACTIVATED CARBON
Abstract: A high surface area activated carbon, prepared from anthracite from the Yunnan Province of China by activation with KOH, was used as the electrode materials of electric doublelayer capacitor (EDLC). The influences of the ratio of activating agent to anthracite in yield, pore structure and specific capacitance of activated carbon as well as its chargedischarge performance as EDLC were studied. The results show that the yield of the activated carbon decrease while its specific surface area and total pore volume increase gradually with increasing ratio of KOH to anthracite. The bielectrode specific capacitance of the activated carbon can reach 73.6?F/g under suitable technology conditions. The EDLC with the activated carbon as electrodes has a good performance in charge and discharge.
