采用以七水合硫酸亚铁(FeSO4·7H2O)为铁源，磷酸(H3PO4)为磷源，以改进的均相沉淀法制备的超细(纳米)FePO4为前驱体，讨论了高温固相碳热还原法的煅烧温度和C添加量对锂电池正极材料LiFePO4形貌和电化学性能的影响。实验结果表明，当煅烧温度为800℃，C添加量为每摩尔FePO432 g葡萄糖，制得的LiFePO4/C的性能较好。

The homemade FePO4, prepared by a reasonable improvement on traditional homogeneous precipitation method, was used as precursor, FeSO4·7H2O as the iron source, H3PO4 as phosphorus source. The calcined temperature and the amount of added C of high-temperature solid-phase carbon thermal reduction method for lithium batteries morphology and electrochemical properties were mainly discussed. The results show that when the calcination temperature is 800℃, C dosage is 32 g glucose per mole FePO4, the prepared LiFePO4/C obtains better performance.
