Abstract：Silicon is considered as one of the most promising materials for the next generation Li-ion batteries to replace widely-used graphite anode materials due to its high capacity, abundant source and environmental friendly. Si/C composite anode materials construct from silicon and carbon for Li-ion batteries, and can not only solve the big volume varaition of silicon and the low capacity of carbon in charge-discharge process, but also integrate the good cycle performance of carbon with the high capacity of silicon. This review summarized recent developments on novel Si/C composites based on the material selection, complex structure and electrode optimization. In addition, the future aspects of developing Si/C composite materials were also prospected.
