Activated carbon is extensively investigated as an electrode for electric double layer capacitor (EDLC) due to its high specific surface area with developed pore structure. The development of pore structure in activated carbon, however, decreases electro-conductivity because the activation process causes defects of carbon crystal structure. It should be, thus, considered that the control of pore structure is an important factor for application in EDLC. In this study, the effect of pore structure on the capacitance and electro-conductivity of EDLC was investigated. The activated carbon was prepared using oxidized pitch as a raw material. The pore structure and electro-conductivity of activated carbon were analyzed using BET and the measurement of sheet resistance, respectively. The capacitance was finally calculated using CV curve. |
