摘要
介绍了橄榄石型L iFePO4正极材料的优缺点和造成L iFePO4导电率和锂离子迁移率低的原因,讨论了近年来各种制备L iFePO4的方法以及改性研究,并对今后的发展方向作出了展望。
The advantages and disadvantages of the olivine-type LiFePO4 cathode material LiFePO4 were introduced,the reasons for Low conductivity and the rate of migration of Lithium-ion were analyzed too.The research progress of preparation,modification and properties in LiFePO4 was briefly described.At the same time,the futher development trend of the material is expected.
