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

摘要: 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 structure can effectively prevent agglomeration of silicon nanoparticles, increase electrical conductivity and reduce transfer resistance Li+. presents high specific capacity good cycling stability (1118 mAh g−1 at 50 mA g−1 up to cycles), well an enhanced rate capability. This approach prepare such porous low-cost facile route silicon-based materials.
