摘　　要：由于二氧化锡(SnO_2)具有价格低、理论比容量高和能量密度高等优点,其作为锂离子电池负极材料被广泛研究。概述了SnO_2基负极材料的储锂机理、发展现状及存在的问题。着重介绍了纳米化、与碳复合手段对改善SnO_2基负极材料电化学性能的作用,并对SnO_2基负极材料发展过程中遇到的挑战提出了建议和展望。Tin dioxide（SnO2）-based materials have attracted much attention as anodes in lithium ion batteries（LIBs）due to their low costs, high theoretical capacities, and high energy densities. The lithium storage mechanism, development status and existing problems of Sn O2-based anode materials were reviewed. The effects of nanostructured SnO2 and its composites（SnO2/C） on improving the electrochemical performances of Sn O2-based anode materials were emphatically introduced. The development prospects of SnO2-based anode materials were proposed, and some suggestions to response the corresponding challenges were provided.
