摘要：

Si/Ag/C composite was prepared by two-step reaction. The phase and surface morphology of samples was studied by XRD and SEM. The electrochemical performance of the composite was investigated by charge/discharge test. SEM images indicate that the particles dispersed uniform and structure of the materials is stable. Electrochemical test results show that the initial discharged and charge capacities of Si/Ag/C composite are 2016.9 mAh/g and 1275.0 mAh/g, respectively. A reversible capacity of Si/Ag/C composite after 50 cycles is 325.5 mAh/g retained.
