A novel highly ordered three-dimensional nanoflower-like alpha-Fe2O3/coal-based graphene (alpha-Fe2O3/CG) composite was fabricated through a simple and controllable hydrothermal synthesis strategy. The nanoflower-like alpha-Fe2O3/CG provides abundant mesoporous morphology, efficient conductive network and rapid electron transfer, as well as unique structural features that all contribute to improved electrochemical performance. Here, alpha-Fe2O3/CG composites have been investigated as advanced anode in the lithium-ion batteries. The electrochemical performance indicated that nanocomposite of alpha-Fe2O3/CG exhibited a high capacity (1000 mAh g(-1)) after 100 cycles at 0.2 A g(-1). In addition, the as-designed composite exhibited excellent cycling stability and even at 5 A g(-1), the specific capacity of it still can achieve 425 mAh g(-1). (C) 2019 Published by Elsevier B.V.
