Abstract: The commercial carbon black was modified for its capacitive behavior in sulfuric acid electrolyte and special application in ultrabattery. The capacitive behavior of the product was studied by cyclic voltammogram (CV) in 4.88mol/L H2SO4 solution. The modified carbon material shows the high specific capacitance of 87 F/g at the scan rate of 20 mV/s and 35 F/g at 500 mV/s while the original carbon black only has a specific capacitance of 25 F/g at 20 mV/s in the same electrolyte.
