活性炭纤维毡直接用作超级电容器电极
Activated carbon fiber felt used directly as electrode for supercapacitor
摘要
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 ACFC was fine due to the open pere structure of fiber and no binder adding in the felt electrode. As the current increased to 20 A/g, the specific capacitance remained 118 F/g.关键词
