The activated mesocarbonemicrobeads will be porous in internal and external part for high performance electrode materials. The aMCMB electrode has a high energy storage capacity. This capacitance of electrode is 350 F g-1 under current is 0.02A g-1. The capacitance of electrode will decrease to 155 F g-1 under current is 0.6A g-1. The study was decreased transfer path of internal ion and raise particle touch for power output of supercapacitor and high rate charge-discharge ability. This capacitance of electrode is 372 F g-1 under current is 0.02A g-1. The capacitance of electrode will decrease to 153 F g-1 under current is 0.6A g-1. The CNTs was added to milling process for raising electron transport and inter-granular pore. This capacitance of electrode is 292 F g-1 under current is 0.02A g-1. The capacitance of electrode will decrease to 177 F g-1 under current is 0.6A g-1.
