英文摘要：

We synthesized LiFePO2C composite cathode materials by the rheological phase method with vegetable protein soya bean milk as a carbon source while FePO4.4H2O and LiOH. H2O as raw materials. X-ray diffraction （XRD） and scanning electron microscopy （SEM） results showed that the LiFePO2C composite materials had good crystallinity, ultrafine sphere-like particles of 200 nm in size and in situ carbon. The electrochemical performance of LiFePO2C by galvanostatic cycling studies showed excellent cycle stability. The LiFePO4/C cathode material gave a high initial discharge capacity of 156 mAh. g-1 at 0.1C and the first columbic efficiency was 98.7%. This capacity was still 149 mAh. g-1 after 40 cycles at 0.1C and its capacity retention was more than 95% while the discharge capacity reached 134.7 mAh.g-1 at 1 C indicating high electrochemical capacity and excellent cycling stability.
