Abstract

Sn thin films as the anode materials of Li-ion batteries were prepared by vacuum-evaporation method on the copper foam substrate.The phase structure,surface morphology and electrochemical property of the as-prepared films were characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM),and galvanostatic cycling.The results showed that three-dimensional structure of copper foam substrate enhanced the adhesion strength between the active material and the substrate,under the same substrate temperature,the particles became bigger with the increasing of evaporation time,while their electrochemical property decreased;under the same evaporation time,the particles didn′t changed obviously with the increasing of substrate temperature,while their cycle life increased.The battery of sample A″(substrate temperature:200 ℃,evaporation time:0.5 h) maintained a discharge capacity of 407.3 mAh·g-1 after 100 cycles.
