| Abstract: | Electrochemical capacitive performance of commercial activated carbon fiber felt(ACFC) used directly as electrode for supercapacitor in 6 mol/L KOH electrolyte was studied.The BET specific surface area of ACFC was 2 066 m2/g with a nitrogen content of 1.48%.The effect of electric double layer capacitance produced by its high specific surface area and the pseudo-capacitance by the nitrogen atom made the specific capacitance of ACFC reach to 194 F/g at the current of 50 mA/g.The high current performance of AC... |
