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.
