Abstract
A uniform and high crystalline Cu0.04V2O5 powder was prepared by precipitation method. The effects of Cu doping on the electrochemical properties of crystalline V2O5 were investigated by means of galvanostatic charge-discharge cycling, cyclic voltammetry and electrochemical impedance spectroscopy. The results showed that slight Cu doping significantly improved the electrochemical properties of V2O5. Cu-doped Cu0.04V2O5 exhibited promising electrochemical performance, with a reversible energy density of 450 Wh/kg and a power density of 275 W/kg.
