Abstract
23 F/cc grade new type of high density activated carbon from crystalline green cokes type of mesocarbon microbeads has been synthesized by chemical and electrochemical activation. In order for these materials to have high performance, electrochemical behavior during electrochemical activation has been investigated by sequential voltage applying schemes. These results showed that the effective voltage for electrochemical activation was about 2.7~3.2 V irrelevant to applying voltage due to the decrease of surface activation of activated carbon with high specific surface area.
