Abstract: SiOx/CoO and SiO/Li2CO3 composite materials were prepared by mechanical ball-milling. The structures of the obtained materials were characterized by X-ray diffraction (XRD). And scanning electron microscopes (SEM) of three samples after 20 cycles were also given. In addition, the electrochemical performances of three materials with galvanostatic charge-discharge cycling were investigated. The results show that the composite samples have larger initial reversible capacities and better cycle performance than pure SiO. Also,a schematic diagram showing the buffer effects of Li2CO3 addition and the mechanism of improving electrochemical performance by adding Li2CO3 are suggested.
