A low cost, up-scalable and one-pot wet-mechanochemical approach is designed for fabricating TiO2-SnO2@graphene nanocomposites where TiO2 and SnO2 solid solution nanoparticles are evenly anchored on graphene sheets. As an anode material of lithium ion batteries (LIBs), the as-prepared nanocomposites deliver a superior rate performance of 388 mA h g(-1) at 1.5 A g(-1) and an outstanding reversible cycling stability (617 mA h g(-1) at 0.4 A g(-1) after 750 cycles, 92.2% capacity retention), due to the synergistic effects contributed from individual components, i.e., high specific capacity of SnO2, excellent conductivity of 3D porous graphene networks, good rate capability and structural stability of TiO2 structures.
