Abstract  Nb-doped LiFePO4/C was synthesized using one-step solid-state method. The effect of Nb contents on the electrochemical performance was investigated. The results showed that the electrochemical performances were remarkably promoted. The discharge capacities of Li0.96Nb0.008FePO4/C cathode material were 161, 148, and 132 mAh•g−1 at the charge and discharge rates of 0.5C, 1C, and 2C, respectively. The results of cyclic voltammetry and EIS analyses showed that the resistance and polarization of the LiFePO4/C composite electrode could be effectively decreased by Nb doping, which would improve the electron conductivity of LiFePO4.

Key words： Lithium ion battery      Cathode material      Nb doping      LiFePO4/C      Electrochemical performance
