Synthesis and Superior Anode Performances of TiO2–Carbon–rGO Composites in Lithium-Ion Batteries

In this article, TiO2–Carbon–rGO (GCT) three-component composite material has been constructed by anchoring TiO2nanoparticles (NPs) encapsulated in carbon shells onto reduced graphene oxide (rGO) sheets. The structure of GCT was characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), N2adsorption–desorption isotherms, and transmission electron microscopy (TEM). This material shows a superior retention as the anode materials in lithium ion battery with a specific discharge capacity of 188 mA h g–1in the initial cycle and 158 mA h g–1after 100 cycles.
