The CoSnx alloys with different atom ratio (x=2, 4, 8) were prepared by solid phase reduction reaction through mechanical ball milling. The structure and morphology were represented by X - ray diffraction (XRD) and scanning electron microscopy (SEM). the elctrochemical performance of the alloy as anode material of li-ion battery was investigated by assembling the analog battery.The experimental results reveal that the nanostructured amorphous CoSn4 shows a relatively high initial discharge capacity (430 mAh/g) and good cycling performance, as its capacity still maintain at 360 mAh/g after the 15th cycle, with a capacity retention ratio of 84 %.
