摘要
介绍了按炭素材料的定向程度和定向方式的结构特征对其进行分类的方法；综述了近年各种炭材料作为锂离子电池负极的较新研究进展，着重分析了石墨、焦碳和不可石墨化碳在放电容量、不可逆容量损失、充放电电位和充放电速率等主要性能上的差异及与他们的结构之间的联系；并简要介绍了各自可能的嵌入机理。
The classification of carbon material according to its structural characteristics of orientational mode and degree is presented in this paper.New developments in recent years of various carbon anode materials for lithium-ion batteries are reviewed.Main differences among graphite,coke and nongraphitic carbon in capacity,irreversible capacity losses,charge/discharge potentials and rates and their relation with the structures are analyzed.The possible intercalation mechanisms are briefly discussed.
