摘　　要：综述了近几年来采用高温固相法、共沉淀法、水热法和微波法等制备锂离子电池正极材料LiFePO4的研究进展。比较了各种方法的优缺点,如高温固相法操作简单,但材料的均一性较差;微波法可快速制备材料,但反应过程难以控制。简要评述了LiFePO4的发展前景。Research progress in preparing LiFePO4 cathode material for Li-ion battery by high-temperature solid state method, co- precipitation method, hydrothermal method and microwave method in recent years was summarized. The advantages and disadvan- tages of different methods were compared. The high-temperature solid state method was simple,but the uniformity of the material was poor; the microwave method could prepare the material quickly, but the reaction process was difficult to control. The develo- ping prospects of LiFePO4 were briefly discussed.
