真空蒸镀法制备锡薄膜及其嵌锂电化学性能
Preparation of Sn Films by Vacuum Evaporation and Their Electrochemical Properties as Lithium-Storage Materials
摘要
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 as-prepared 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.关键词
