| Abstract: | The structure and the characteristic of new electrode material LiFeP O4 for lithium-ion battery were introduced in this paper. The three main method s of LiFePO4 preparation including hydrothermal process , high temperature solid state reaction and co-precipitation process as well as the analysis results of LiFePO4 with SEM were described. The mechanism of capacity loss of LiFePO4 and the countermeasure were outlined. It was believed that , at present, improving t he electronic conductivity of LiFePO4 was the main way to suppress the capacity loss of LiFePO4. |
