A series of cathode materials for lithium-ion batteries with the formula (MoO3)1-x(V2O5)x (x = 0.00; 0.01; 0.02; 0.03; 0.04) were synthesized by high-temperature solid-state method. The effects of V2O5 on the structural; morphology and electrochemical properties of the cathode materials were investigated through X-ray diffraction (XRD); scanning electron microscopy (SEM); charge-discharge test; cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) experiments. The results show that cathode materials exhibit better electrochemical performance after V2O5 doping. (MoO3)0.98(V2O5)0.02 shows the highest first discharge capacity of 280.6 mAh g-1and the best cycling reversibility. © 2009 Elsevier B.V. All rights reserved;
