Si/C@graphene(GR)/graphite(G) composite anode materials were prepared by a simple and easy-to-operate wet coating method with silicon nanoparticles and graphite as main raw materials, fatty alcohol polyoxyethylene ether as a surfactant and graphene. The effect of allocation ratio on the composition, morphology and electrochemical performance of the composite materials was investigated. The results show that the prepared composite materials exhibit a superior cycling stability, and the volume expansion alleviates. When the silicon nanoparticles content is 10%, the initial discharge capacity is approximately 730 mA·h/g. After 100 cycles at a current density of 100 mA/g, the discharge capacity can stably maintain at 500 mA·h/g. The initial coulomb efficiency reaches 87.27%, revealing a great improvement in comparison with the efficiency of pure silicon material (i.e., less than 70%).
