LiFePO4正极材料倍率性能改善的研究进展
Research process in rate performance of LiFePO4 cathode materials
摘要
Abstract
Olivine-type lithium iron phosphate (LFP) was used as cathode material of lithium ion battery due to its good electrochemical performance,such as stable charging and discharging platform and steady structure during cycling of Li ions.What's more,it had high safety,non-toxic and polluting-free,as well as long cycle life and rich raw material.However,there was a instinct drawback of olive structure that baffles the marketization of LEP in the field of electrical vehicle,and that was the poor rate performance.The main approaches to improve rate performance of LEP include ion doping,surface coating,nanocrystallization,ect.On the base of improved approaches mentioned above,the methods in enhancing rate performance of LFP were reviewed in recent years.关键词
