摘要
作为聚阴离子型锂离子电池正极材料,单斜结构Li3V2(PO4)3及橄榄石型LiFePO4因具有结构稳定、循环性能优良及安全性能好等突出优点而日益为人们所关注,成为极具开发和应用潜力的新一代锂离子电池正极材料,尤其是在对材料要求较高的动力电源领域的应用。但由于两者均存在影响电化学性能的低电导率问题,因此提高电导率已成为研究这两种材料的重点。本文主要介绍了近年来磷酸铁锂和磷酸钒锂的研究现状及成果,并对今后的发展进行展望。
As anode material for lithium ion battery,Li3V2(PO4)3and LiFePO4 become more and more attention by people owing to its stable structure,good cycle performance and safety performance is better for other prominent advantages,and become a great development and potential applications for lithium ion battery cathode material,especially in the applications of materials to demand higher power supply.Because of the low electrical conductivity,the methods to improve the electrical conductivity has become the focus of the study among the two kinds of material.This article mainly introduced the lithium iron phosphate and the present research situation in recent years,it also described the development in the future.
