We designed and fabricated a gold (Au)-coated nanowires/graphene (Au-SiNWs/G) hybrid composite as a polymer binder free anode for rechargeable lithium ion batteries (LIBs). A large amount of SiNWs for LIB anode materials can be prepared by metal assisted chemical etching (MaCE) process. The Au-SiNVVs/G composite film on current collector was obtained by vacuum filtration using an anodic aluminum oxide (AAO) membrane and hot pressing method. Our experimental results show that the Au-SiNVVs/G composite has a stable reversible capacity of about 1520 mA h/g which was maintained for 20 cycles. The Au-SiNWs/G composite anode showed much better cycling performance than SiNWs/ polyvinylidene fluoride (PVDE)/Super-P, SiNWs/G composite, and pure SiNWs anodes. The improved electrochemical properties of the Au-SiNWs/G composite anode material is mainly ascribed to the composite's porous network structure.,(C) 2014 Elsevier B.V. All rights reserved.
