英文摘要：

The status of development on anode materials for lithium ion batteries in recent years were summarized, focusing on the preparation methods, characteristics, problems and improvement ways of tin-based oxide, tin-based composite oxide, tin-based alloy and tin-based composite, respectively. It indicates that a single approach is difficult to comprehensively improve the performance of the tin- based materials, and an integrated application of various methods such as optimizing the structure, controlling components of the materials, incorporating matrix into the tin-based materials as well as optimizing the reducing agent, binder and electrolyte additives can improve the electrochemical per- formance of the anode materials. Finally, the research trend in tin-based anode materials is prospec- ted,and also it is pointed out that the tin-based composite materials with graphene as matrix may be one of the most promising research directions for future.
