Preparation of Sn Films by Vacuum Evaporation and Their Electrochemical Properties as Lithium-Storage Materials
Abstract:
Sn thin films on Cu foil substrate were prepared by vacuum evaporation and investigated as the anode materials of rechargeable lithium-ion batteries.The surface morphology and composition of the asprepared films were characterized by scanning electron microscopy(SEM) and X-ray diffraction(XRD).The electrochemical performance of the film electrodes was measured using CR2032 coin-type cells.The experimental results show that the deposited films are composed of nano/micro particles,which are enlarged with increasing both the evaporation power and the substrate temperature.This behavior is correlated with the electrochemical performance of the film electrode.It is found that at 200 W and 150℃,the thin film with small particle of Cu6Sn5 phase displays a discharge capacity of 527 mA·h/g after 20 cycles.
