摘要
综述了锂离子电池锡基金属间化合物和复合物负极的研究进展。介绍了锡基合金体系作锂离子电池负极的优势,指出了锡金属负极的不足,提出了采用锡基合金及其复合物是克服锡金属负极主体材料尺寸稳定问题的解决办法。概述了各种锡基合金和其复合物的结构、电化学性能、相应的加工方法和某些反应机理,总结了这些材料的优点和缺点,提出了改进这些材料性能的一些建议,如采用分散形态的纳米颗粒结构或用非晶合金并控制形态结构的转变,着重指出多相锡基锂合金复合物是最有前景的负极材料。
The recent advance of tin-based alloy as candidate anodes for secondary lithium batteries is reviewed in this paper. The structure, electrochemical performances, preparation and reaction mechanisms of tin-based alloys and their composites are summarized. The advantages and shortages of these materials are analyzed and the solutions to improve their performance are suggested, such as adopting nano-scale particle structures with scatter configuration, utilizing amorphous alloys or controlling the change of structure conformation. The muhiphase tin-based lithium alloy composites anodes for Li-ion batteries are proposed to be the most promising alternative anode materials.
