| Abstract: | Sn/C composites were prepared by using a convenient high energy ball-milling technique,followed by solid phase synthesis process.The characteristics of the composites as anode material for rechargeable lithium-ion batteries were investigated by X-ray diffraction(XRD) and scanning electron microscopy(SEM) methods.The electrochemical performance of the anode material was studied,and it was found the composite anode had a high capacity of ca.566.4 mAh?g-1.Such prepared materials displayed improved cycle life. |
