摘　　要：总结了三种不同离子掺杂改性方法对磷酸铁锂(LiFePO4)电极材料倍率性能的影响研究现状。单离子掺杂改性LiFePO4材料制备方式简单且改性LiFePO4材料倍率性能优异,研究最为广泛;双离子掺杂改性LiFePO4材料倍率性能提高的同时,循环性能显著提升,也是目前的研究热点;多离子掺杂改性LiFePO4材料机理复杂,有待深入研究。The influence of three different ion doping modification methods on the rate performance of LiFePO4 electrode material were summarized in this paper.it is concluded that the single ion doping modified LiFePO4 material is the most extensively researched material for its easy preparation and excellent rate performance;the double ion doping modified LiFePO4 material is the current research hot spot for both its improved cycle performance and rate performance;the mechanism of multi-ion doping modified LiFeP04 is complex and requires further study.
