中文摘要：
在机械球磨过程中通过固相还原反应制备了不同原子配比（2：1，4：1，8：1）的Sn-Co合金，采用X射线衍射（XRD）和电子扫描电镜（SEM）分析了其结构和形貌，并通过组装模拟电池考察了该合金作为锂离子电池负极材料的电化学性能．实验结果表明：具有非晶纳米结构的CoSn4合金具有较高的初始放电容量（430mAh／g）和良好的循环性能，15周后仍能放出360mAh／g的容量，容量保持率为84％．
英文摘要：
The Sn Co alloys with different atom ratio（2： 1, 4： 1, 8： 1） were prepared by solid-state reducing reaction through mechanical ball milling. The structure and morphology of the products were characterized by means of powder X-ray diffraction and scanning electron microscopy, the elctrochemical performance of the materials used as lithium intercalation anode was investigated using simulated test cells. The experimental results reveal that the nanostructured amorphous CoSn4 exhibite a relatively high initial discharge capacity （430 mAh/g） and good cycling stability,as it can still deliver a discharge capacity of 360 mAh/g after the 15th cycle, with a capacity retention ratio of 84%.
