Electrochemical performance of the Si/graphene composites. (a) Cycling stability of the composites obtained in different Si nanoparticles and graphene weight ratios. (b) Long-term cycling stability of the Si/graphene composites under current density of 100 mAg−1. (c) Charge/discharge profiles of the Si/graphene composites obtained after one, two, four, fifty, eighty, and one hundred cycles. (d) Rate performance of the Si/graphene composites.
