Abstract
A novel highly ordered three-dimensional nanoflower-like α-Fe2O3/coal-based graphene (α-Fe2O3/CG) composite was fabricated through a simple and controllable hydrothermal synthesis strategy. The nanoflower-like α-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, α-Fe2O3/CG composites have been investigated as advanced anode in the lithium-ion batteries. The electrochemical performance indicated that nanocomposite of α-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.
