摘要

LiFePO₄正极材料具有循环寿命长、安全性能高、环保性好等优点,被广泛应用于电动汽车及电子设备等领域。但由于其工作电压较低,限制了其在大功率电池中的应用。基于LiFePO₄单一正极材料,将橄榄石结构LiMPO₄同类材料(M=Fe、Mn、Co、Ni及这些元素的混合)互掺杂得到的高能量密度二元/三元固溶体正极材料,能有效解决以上问题。因此,总结了该材料的研究现状,并对其电化学性能进行分析,最后指出了现阶段该材料在实际应用中存在的问题,并对其未来发展趋势进行了展望。

Abstract

LiFePO₄ cathode material is widely used in the fields of electric vehicles and electronic equipment due to its long cycle life,high safety performance,and good environmental protection.However,the low operating voltage has limited its application in high-power batteries.Based on LiFePO₄ single cathode material,the binary/ternary solid solution cathode material obtained by inter-doping similar materials of olivine structured LiMPO₄(M=Fe,Mn,Co,Ni and mixture of these elements) can effectively solve the above problems,and obtain high energy density Li-ion battery.Therefore,summarizing the research status of the material,analyzed its electrochemical performance,and finally pointed out the problems in the actual application of the material at this stage.The future development trend of the material was prospected.
