Abstract

The impact of nickel oxide (NiO) impregnation in enhancing the performance of a carbon electrode in electrochemical capacitors (EC), was analyzed. Polyacrylonitrile-based activated carbon fabric (CF) was used to fabricate the carbon electrode of the ECs. Carbon containing 1, 3, 4 and 5 wt.% NI were obtained by adding Ni(NO3)2 solutions of different concentrations to the carbon support and then drying the mixtures at 110°C under vacuum. The results show that the resistance of Ni-loaded cells decreases with the heat treatment temperature and is smaller than that of the CF.
