In this job, the graphite was introduced to Lithiumion battery LiFePO4 anode material to fabricate LiFePO4/Graphite composite material.At first, Carbon coated LiFePO4 precursor was prepared by high temperature solid phase synthesis method using LiCO3, FeC2O42H2O, (NH4)2HPO4 and C6H12O6 as raw materials, then different percentage of graphite was added by a solid powder mixed process to obtain LiFePO4/Graphite composite material.The obtained composite materials were assembled into button battery to test the electrochemical property.The testing results show that the electrochemical performance has been improved greatly.Compared with LiFePO4 matrix material, the first time discharge capacity of LiFePO4+1wt% graphite Composite material increased from 131.75mAh/g to 146.51 mAh/g at 0.1C rate.The charging and discharge performances of LiFePO4+1wt%graphite Composite materials have been improved by 5.8% and 4.8%, respectively.
