▎ 摘　　要

In this work, a solvothermal method combined with a hydrothermal two-step method is developed to synthesize graphene-SnO2-TiO2 ternary nanocomposite, in which the nanometer-sized TiO2 and SnO2 nanoparticles form in situ uniformly anchored on the surface of graphene sheets, as high stability and capacity lithium-ion anode materials. Compared to graphene-TiO2, bulk TiO2 and grapheme-SnO2 composites, the as-prepared nanocomposite delivers a superior rate performance of 499.3 mAhg(-1) at 0.2 C and an outstanding stability cycling capability (1073.4 mAhg(-1) at 0.2 C after 50 cycles), due to the synergistic effects contributed from individual components, for example, high specific capacity of SnO2, excellent conductivity of 3D graphene networks.
