摘要

The lithium-ion battery anode materials TiO2/rGO were synthesized from different layers of graphene oxide (GO) and Titanium oxysulfate using hydrothermal method.The structure and morphology were studied by X-ray diffraction (XRD),scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR).Their electrochemical performances were tested through galvanostatic charge/discharge and electrochemical impedance spectrum (EIS).The test results show that the TiO2/rGO (few-layers) composites exhibited better electrochemical performance than the TiO2/rGO (multi-layers) composites.At the current density of 100 mA/g,the discharge capacity of TiO2/rGO (few-layers) is 285.3 mAh/g after 100 cycles,and the Coulombic efficiency is still maintained as high as 98.6%,which is superior to that of the TiO2/rGO (multi-layers).TiO2/rGO (few-layers) electrode shows good rate capability and enhanced electrochemical performance compared with the TiO2/rGO (multi-layers) electrode.
