N2  - It is suggested that the specific capacitanceC0 of activated carbons at lowcurrent densities (d¡«1mAcm.2)consists, to a good first approximation, of two contributions. For theH2SO4 electrolyte they correspond to approximately 0.080 Fm.2 from the total accessible surface area and an additional pseudo-capacitance of 63 F mmol.1 from the surface species generating CO in thermally programmed desorption (TPD). The new correlation proposed here is an alternative to Shi¡¯s earlier approach which considered contributions from the microporous and the external surface areas. Furthermore, it appears that the variation of the specific capacitance C at high current densities d (up to 100¨C150mAcm.2)depends essentially on the CO2-generating surface groups and on 1/L0, the inverse of the average micropore width
