摘　　要：作为一种新型锂离子电池负极材料,二氧化锡由于具有高比容量、低嵌锂电势等优点而受到了广泛关注。但是二氧化锡在充放电循环中体积变化过大,导致其不可逆容量损失大、循环性能较差。纳米化和合金化是解决这一问题的有效途径。综述了纳米结构二氧化锡及其复合材料,特别是二氧化锡纳米线、纳米棒、纳米管、纳米片等与无定形碳、碳纳米管、石墨烯的复合材料在锂离子电池负极材料中的研究进展,并展望了其应用前景。As a novel anode material for lithium ion batteries, tin oxide has attracted much attention owing to its high specific capacity and low lithium insertion potential. However, the large volume change during the charge-dis- charge process leads to severe irreversible capacity fading and poor cycling performance. Design of nanostructured tin oxide and its composites has proved to be an efficient way to solve this problerrL The research progress and application prospect of nanostructured tin oxide, especially of SnO2 nanowires, nanorods, nanotubes, nanosheets and their com- posites with amorphous earbon, carbon nanotubes and graphene as anode materials for lithium ion batteries, are re- viewed.
