▎ 摘　　要

High capacity silicon electrode with low cost is deemed as the promising anode material for the future Li-ion batteries with the replacement of graphite anode. In this work, robust defected graphene layers wrapped silicon/nanorod carbon (Si/NRC@DG) is synthesized through evaporation-induced self-assembly method for high lithium ion storage. Results show that the rapid conductive network formed by nanorods and defected graphene shorten the electron/lithium ion pathway to reach Si nanoparticles, enhancing the utilization. Meanwhile, the unique three-dimensional nano-architecture accommodates the large volumetric expansion of Si, immerses the electrolyte and facilitates efficient lithium ion diffusion. As a result, the so-synthesized Si/NRC@DG electrode exhibits a remarkable capacity of 669 mA h g(-1) at 0.1 A g(-1) after 100 cycles. Coupled with LiFePO4 cathode, the assembled full cell is capable of offering an initial capacity of 126 mA h g(-1), providing opportunities for realizing high energy lithium ion batteries.
