Si-SiOx/rGO/PPy composite is successfully synthesized via in-situ polymerization process, and then investigated by X-ray diffraction (XRD), scanning electron microscope (SEM),transmission electron microscopy (TEM), infrared Spectroscopy (IR) and charge-discharge test. It is proved that SiSiOx/rGO/PPy composite possesses much better electrochemical performance in comparison with SiSiOx and Si-SiOx/rGO composites. It possesses a reversible lithium capacity of 1478.3 mAh·g -1 at 100 mA·g -1 , and 30.4% of its capacity is remained after 70 cycles.
