Research Progress on Tin-based Anode Materials for Lithium Ion Batteries

Abstract

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 performance of the anode materials. Finally, the research trend in tin-based anode materials is prospected,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.
