Effects of glucose addition on properties of LiFePO_4/C materials

In this paper,microstructure and electrochemical properties of LiFePO4/C materials prepared by solid-liquid technique with glucose as the carbon source were studied by X-ray diffraction,scanning electron microscope and electrochemical testing.The results show that small and even LiFePO4/C materials are obtained by adding glucose.When mass fraction of glucose is 9%,LiFePO4/C materials evenly coated by carbon film exhibit a good physical appearance and electrochemical properties.The electrochemical testing indicates that maximum discharge capacity of LiFePO4/C materials is 143.6mAh ·g-1 under 0.2C constant current,and discharge capacity conservation rate is 94.8% after 30 cycles.
