| 摘 要： | 磷酸铁锂（LiFePO4）具有高温稳定性较好、循环性能良好、环保等特点,已成为锂离子动力电池正极材料之一。但由于磷酸铁锂电导率低及锂离子扩散速率慢等缺点,制约其在动力电池行业的发展。因此主要从包覆碳材料对磷酸铁锂进行表面改性、对磷酸铁锂进行掺杂、制备亚微米或纳米级的磷酸铁锂或制备特殊形貌的磷酸铁锂3方面进行综述,分析改善磷酸铁锂性能最优的方法,对其未来的发展趋势进行了预测。

| Abstract: | LiFePO4 has the characteristics of high temperature stability,good cycle performance and environmental protection etc..It has become one of the cathode materials for lithium ion power batteries.However,due to the low electronic conductivity of LiFePO4 and the slow diffusion rate of lithium ions,the application of LiFePO4 in power battery industry is restricted. Therefore,it was summarized the improvement of LiFePO4 from three aspects：surface modification of LiFePO4 with carbon coated materials,doping LiFePO4,preparing submicron or nanometer LiFePO4 or the LiFePO4 with special morphology.The optimum method of improving LiFePO4 was analyzed and its development trend in the future was predicted. |
