CNT is getting into the spotlight due to batteries, and supercapacitor. But it is surface area smaller than activated carbon. So, MWNT coated electrode of activated carbon were researched for improving of surface area of electrode by charging surface. Such as, charging surface of MWNT and activated carbon were prepared by functionalization. Characterisitic of electrochemical was analyzed by cyclic voltammetry and AC impedance measurement in coin cell. So, AC impedance and Cyclicvoltammetry measurements show that MWNT coated electrode of activated carbon are promising electrode materials for high-power and high-energy electrochemical devices. |
