Abstract

Mesoporous nanomaterial has been extensively studied in high-performance anode materials, because of their large electrolyte–electrode contact area, small volume change, high safety and enhanced specific capacity during discharge/charge process. Herein, we use titanium trichloride as Ti-sources and adjust the pH of solvent to successfully prepare mesoporous nanoplate TiO2 on reduced graphene oxide (RGO) nanosheets via two-step hydrothermal treatment. Benefiting from the unique structure, as-prepared mesoporous nanoplate TiO2/RGO composites present high reversible capacity and strong cycling stability (high capacity of ∼200mAhg−1 at 1.2C after 300 cycles) as anode materials for Li ion batteries (LIBs).
