to bring a high specific capacitance. SOFFER and KORESH et al[3-4] proposed that the pores with size larger than 0.5 nm can be utilized in KOH aqueous system. LIN et al[5] reported that the smallest pore size which can form double layer in H2SO4 system is 0.8 nm. ZULETA et al[6] detected the ionic diameters of Et4N+ and BF4- to be 0.68 and 0.45 nm, respectively. The popular conclusion......
