Electrochemical double layer capacitors (EDLCs) store electrochemical energy via adsorbing electrolyte ions on the electrode surface; thus high surface area and electrical conductivity are necessary. Therefore, there are tremendous efforts to increase the surface areas, mainly achieved from development of micropores and small mesopores, and electrical conductivity via incorporation of nitrogen atom for high performance of EDLCs. There have, however, been less focused on the effect of relatively large mesopores (> 10 nm) for capacitance of EDLCs. In this poster, we synthesized 3-dimensionally ordered mesoporous carbons (3DOmCs) by hard template method through infiltration the carbon precursor into the silica templates (20-50 nm). Capacitances of EDLCs of the different sizes of mesopores (20, 40, and 50 nm) of 3DOmCs with similar surface areas were investigated and the correlation between the size of mesopores and capacitances will be presented. In addition, in order to more boost the capacitance, CO2-activation process was applied to develop surface area of 3DOmCs.
