摘　　要：SnO2是一种重要的宽禁带半导体材料,由于具有较高的理论容量,将其作为锂离子电池的负极材料有广阔的应用前景。材料的微观形貌对其物理化学性能有重要的影响作用,因此近年来大量的研究工作围绕SnO2的形貌调控合成开展。本文综述了作为锂离子电池负极材料SnO2的各种形貌的调控合成,如颗粒状、片状、一维、空壳、分级结构等,以及其形貌对电化学性能的影响,分析总结了各种形貌对其电化学性能的影响规律以及形貌调控的发展趋势。SnO2 is an important wide band-gap semiconductor material, which has broad application prospects as an anode material for lithium-ion battery due to its high theoretical capacity. In recent years, many studies have been carried out on the morphology-controlled synthesis of SnO2 because the micro-morphologies of the materials have an important impact on their physical and chemical properties. This paper reviewed morphology-controlled synthesis of SnO2 with various morphologies, such as particle, sheet, one-dimensional, hollow, hierarchical structures, etc. which is used as an anode material for lithium-ion battery, as well as the effects of their morphologies on their electrochemical performance. The effect of the various morphologies on their electrochemical properties and the development trend of the morphological control are also analyzed and summarized.
