磷酸铁锂(LiFePO4)作为动力锂离子电池正极材料,具有良好的热稳定性、平稳的充放电平台。然而由于其本身结构的缺陷,导致其倍率性能和低温性能较差,这将影响该材料在电动汽车市场的应用。改善其性能的方法主要有表面包覆、体相掺杂等手段。本文综述了近年来LiFePO4性能改善的研究进展。
Abstract：Due to high thermal stability,stable charge-discharge performance,LiFePO4(LFP)is widely used as cathode material for lithium-ion power batteries.However,there is an instinct drawback because of olive structure,which results in worse rate performance and low temperature performance and finally affects its commercial application in the field of electrical vehicle.In this paper,we comment some strategies to improve performances of LFP,including surface modification,element doping.
