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.
