Abstract

A uniform and high crystalline Cu_0.04V₂O₅ 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 Cu_0.04V₂O₅ exhibited promising electrochemical performance, with a reversible energy density of 450 Wh/kg and a power density of 275 W/kg.
