▎ 摘　　要

Graphitized carbon (GC) and graphene (GE) modified Fe2O3/Li4Ti5O12 (LTO) composites have been synthesized via a solid-state reaction, respectively. The structure, morphology and electrochemical performance of the materials have also been characterized with X-ray diffraction (XRD), scanning electron microscope (SEM) with an energy dispersive spectroscopy (EDS) system, X-ray photoelectron spectrometer (XPS). Fourier transform infrared spectroscopy (FTIR) and electrochemical measurements. The discharge capacities of Fe2O3/LTO, GC/Fe2O3/LTO and GE/Fe2O3/LTO are 100.2 mAh g(-1), 207.5 mAh g(-1) and 238.9 mAh after 100 cycles at the current density of 176 mA g(-1). The cyclic stability and rate capability are in the order of GE/Fe2O3/LTO GC/Fe2O3/LTO > Fe2O3/LTO because of the synergistic effect between GC (GE) and Fe2O3/LTO.
