摘　　要：应用控制结晶法从溶液相制备球形FePO4.xH2O,再高温烧结得到FePO4前驱体,最后用微波碳热还原法合成高密度L iFePO4/C.由XRD和SEM表征该材料的结构、形貌,并测试其电化学性能.The spherical FePO4 · xH2O was prepared in the solution by controlled crystallization. The precursor FePO4 was obtained in high temperatureceramie approach, then the high density LiFePO4/C was synthesized by microwave carbon thermal reduction. The structure and morphology of the materials were characterized by means of XRD and SEM techniques, and the electrochemical properties were studies by charge-discharge experiments.
