Nitrogen-enriched carbon materials were prepared by the heat-treatment of polyaniline (PANT). The electrochemical capacitance of the carbonized PANI in 1.0 mol dm-3 H2SO4 electrolyte depended on the heat-treatment. The carbonized PANI at 800°C showed good cycle performance and 157 F·g-1 of the gravimetric capacitance. The capacitance is lower than the original PANI, but it is comparable to conventional activated carbon fibers (ACF). The specific capacitance per BET surface area for the carbonized PANI was about 40 times as much as that for the ACF. The capacitance of the carbonized PANI was not correlated with the BET specific surface area, but strongly depended on the electronic conductivity and the nitrogen content. These results suggest the redox center of nitrogen-containing surface functionalites rather than the double layer charging as the capacitance origin for the carbonized PANI.
