摘　　要：采用高温固相反应法,分析了不同反应温度对制备LiFePO4/C复合材料的影响,研究了制备LiFePO4/C复合材料的最佳温度。试验结果表明,在650℃合成的产物,颗粒尺寸细小,分布均匀,放电容量高,循环稳定性好,此制备温度最佳。The effects of reaction temperature on the preparation of LiFePO4/C composite material were analyzed by solid-state reaction at high temperature; the optimum temperature of preparing LiFePO4/C composite material was studied. The test results show that, when preparing at 650℃, the synthesis product is small and homogeneous in size, and has large discharge capacity and good cycle actability, which shows that the preparation temperature is optimum.
