▎ 摘　　要

The stable high-capacity anode has been an urgent demand for high energy density lithium-ion batteries (LIBs). Herein, a simple and effective strategy to synthesize high-performance reduced graphene oxide (rGO) in-situ wrapped MnTiO3 nanoparticles (MnTiO3@rGO) by Sol-Gel method is designed. The MnTiO3 nanoparticles are uniformly dispersed and wrapped by few-layer graphene. Due to high conductivity of rGO, MnTiO3@rGO nanoparticles show excellent rate performance, with a specific capacity of 286 mAh.g(-1) being displayed at the higher rate of 5.0A.g(-1). Moreover, benefited from porous structure and flexible rGO shell, the MnTiO3@rGO anode delivers a remarkable long-term cycling stability. The specific capacity maintains 441 mAh.g(-1) after 500 cycles at 0.5 A.g(-1), only losing 8.4%. Therefore, the results demonstrate that the facile synthetic strategy is highly desirable for improving the conductivity and stability of metal oxide anodes.
