Abstract

Carbon is an attractive candidate for use in eletrochemical supercapacitors that depend on charge storage in the electrode/eletorlyte international double layer. Property of an electrical double layer capacitor depend both on the technique used to prepare the electrode and on the current collector structure. The study is to research that $V_2O_5$-carbon (SP270) composite electrode for supercapacitor. The discharge capacitance of $V_2O_5$-SP270 (20wt%) in 1st and 35cyc1e was 14F/g and 8.5F/g at current density of $0.1mA/cm^2$. The discharge process of $V_2O_5$-SP270 (20wt%) composite electrode is larger than that others.
