摘　　要：锡基负极材料与碳负极材料相比,具有容量密度高,安全性好等优点,成为动力锂离子电池用新型负极材料研究的热点之一。本文综述了近年来国内外针对锡基材料首次不可逆容量高、循环性能差等问题所进行的改性研究,分别从材料的制备方法、组成结构及电化学性能等方面进行比较分析,并对锡基负极材料的进一步研究、发展应用予以展望。Compared with carbon anode materials, tin-based anode materials have advantages of high capacity density and good safety, which therefore become one of the research hotspots in novel anode materials for power lithium ion battery. The research progress of tin-based anode materials in recent years are presented in this paper with focuses on the problems of high irreversible capacity in the first cycle and poor cycle performance. Moreover, the comparison and analysis in material preparation methods, structures and electrochemical performances are also provided.
