中文摘要：
通过球磨的方法制备了锡锑合金／石墨复合材料，应用XRD、SEM和电化学方法对锡锑合金／石墨复合材料的微观结构和电化学性能做了研究。复合材料的首次可逆容量达到416mAh／g，锡锑合金／石墨复合材料的循环稳定性相比于锡锑合金有了很明显的改善。对锡锑合金含量与复合材料吸放锂性能的研究表明，含锡锑合金50％的锡锑合金／石墨复合材料循环稳定性最好，到第20个循环时，容量保持率为88％（锡锑合金为81％），是有希望的锂离子电池负极材料。
英文摘要：
SnSb alloy-graphite composites have been prepared by ball-milling a mixture of SnSb alloy and graphite powder. The microstructure and electrochemical performance of the composites are characterized by X-ray diffraction,SEM and an electrochemical method. The mechanism of lithium ions adsorption/extraction in the composites was found to be lithium ions reaction with SnSb and graphite. The reversible capacities of the composites reached 416mAh/g,SnSb alloy-graphite composite electrodes show better cycleability than SnSb alloy. By analyzing the relation between SnSb contents and the properties of the composites,it is showed that SnSb50%-graphite has the best cycle stability,the capacity retention at the 20th cycle is 88%（81% at SnSb alloy）. These composites appear to be promising candidates for negative electrodes in lithium rechargeable batteries.
