摘　　要：碳材料是目前广泛采用的负极材料,但是低电化学容量一直制约着锂离子电池的发展.锡基材料由于高电化学容量,是一种有巨大发展潜力的锂离子电池负极材料,但仍存在充放电过程中循环寿命差、材料体积变化大、易粉化等问题.因此,需要寻找一种可以结合两种材料优势的方法.简要介绍了碳基、锡基材料的发展现状及存在的问题,并简述了碳锡复合材料的研发方向及前景.Carbon materials are widely used as anode materials,but low electrochemical capacity has restrict-ed the growth of lithium ion battery.Tin based material is of huge potential due to its high electrochemical capaci-ty,but still has such problems as poor cycle life in process of charge and discharge,great volume changes,and less chalking resistance.Therefore,it is necessary to find a way to combine the advantages of the two.This paper brief-ly introduces the present development and the existing problems of carbon based and tin based materials,further-more,it points out the direction and prospect of carbon -tin composite material research.
