Abstract: The structures, electrochemical performance, reaction mechanisms and preparation methods of Sn-Co alloys and Sn-Co-C ternary composites for Li-ion batteries are summarized. According to the current literature, cycle performance of Sn-based materials could be improved by diversification by adding other elements; reducing the size of grains or changing into amorphous state. At present, the problem could not be solved successfully by a single approach. In order to satisfy the demands of cycle performance in commercialization, applying a comprehensive approach has become a development tendency.

摘要： 综述了锂离子电池锡钴二元合金和锡钴碳三元复合材料的结构、电化学性能、反应机理及制备方法。改善锡基材料的循环性能主要有3个途径：元素多元化，减小颗粒粒度，无定形化。仅靠上述单一途径很难达到产业化对循环性能的要求，因此多种途径联合运用成为解决循环性能的研究趋势。
