The olivine LiFePO4/C composite cathode materials for lithium-ion batteries were synthesized by solid state reduction method using mixed iron sources. The effects of different temperatures on the electrochemical performance of as-synthesized cathode materials were investigated and analyzed. The crystal structures and the electrochemical performances were characterized by SEM, galvanostatical charge-discharge testing and AC-impedance, respectively. The results demonstrated that the LiFePO4/C composite cathode material synthesized at 710°C and with 1/2(FeC2O4·2H2O/Fe2O3) molar ratio of mixed iron sources has the better electrochemical performance, it has a discharge capacity of 126.1mAh/g at 0.2C and the capacity is kept at 113.8mAh/g after 20 cycles.
