Abstract Si@C/graphite composites were synthesized based on the industrial nano-silicon via spray drying and thermal pyrolysis method,and the structure, morphology and electrochemical property of as-prepared composites were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), constant current charge/discharge and cyclic voltammetry (CV). The results indicate that silicon with different nanoscale sizes directly affects composites properties. The smaller the particle size of silicon is, the better stability of composites will become. The cell prepared by Si@C/Graphite composite material which contains 80 nm silicon displays a higher initial discharge capacity of 774.3 mAh/g at 100 mA/g. After 100 cycles,the capacity retention rate is 78.1%.
