Self-assembly of Si/honeycomb reduced graphene oxide composite film as a binder-free and flexible anode for Li-ion batteries

Abstract

A silicon/honeycomb graphene composite film synthesized by the “breath figure” method is developed as a high-performance anode material for lithium ion batteries. The honeycomb graphene structure can effectively prevent the agglomeration of the silicon nanoparticles, increase the electrical conductivity and reduce the transfer resistance of Li+. The composite film presents a high specific capacity and good cycling stability (1118 mAh g−1 at 50 mA g−1 up to 50 cycles), as well as an enhanced rate capability. This approach to prepare such a honeycomb porous structure is a low-cost and facile route for silicon-based anode materials.
