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 bandgap semiconductor material. Due to its high theoretical capacity, SnO2 has wide application prospects as a negative electrode material for lithium ion batteries. The microscopic morphology of the material has an important influence on the physicochemical properties of the material, so a great deal of research work has been carried out around the morphology and control of SnO2 in recent years. In this paper, the synthesis and synthesis of various morphologies of SnO2 anode materials for lithium ion batteries are reviewed, such as granular, flake, one-dimensional, shell, hierarchical structure, and their morphologies on the electrochemical performance. The influence of various morphologies on the electrochemical properties and the development trend of morphology control.
