摘　　要：金属基电极材料相对于传统石墨负极具有更高的容量,有望成为新一代锂离子电池负极材料.但是在长期的充放电循环过程中,金属基电极材料的体积变化较大,导致电池循环稳定性下降、库仑效率降低等问题.中空微/纳米级材料具有表面积大、密度低、承载能力强等特点,最重要的是这类材料可以缓冲电极材料的体积膨胀.本文重点综述了近年来中空微/纳米过渡金属基材料作为锂离子电池负极材料的研究进展,并对该材料的锂储存性能进行了总结.Compared with the traditional graphite anode,metal based materials have higher capacity and are expected to become a new generation of anode materials for lithium ion battery.Nevertheless,during the long-term charge-discharge cycle,the volume of the metal based electrode material changes greatly,which leads to the decrease of the cycling stability of the battery and the decrease of the coulomb efficiency.Hollow micro/nano materials have the advantages of large surface area,low density and strong bearing capacity.The most important is that they can buffer the volume expansion of electrode materials.In this paper,the recent development of hollow micro/nano transition metal based materials for lithium ion batteries is reviewed,and the electrochemical properties of the materials are summarized.
