▎ 摘　　要

Developing high-performance anode materials for rechargeable lithium-ion batteries (LIBs) is of great importance for large-scale applications of electronics and electric vehicles. Here, a silver-doped titanium dioxide nanoparticle on reduced graphene oxide sheet (denoted as Ag-TiO2/rGO) nanocomposite is synthesized through a solvothermal method. With the merits of high surface area of rGO and high conductivity of Ag nanoparticles, Ag-TiO2/rGO shows a competitive reversible capacity of 196.9 mA h g(-1) at a current density of 1C after 100 cycles. Meanwhile, a high rate capability and cyclability can be maintained. After a long-term cycling of 1000 cycles at 5C, the discharge capacity is still as high as 144.2 mA h g(-1) with nearly 100% coulombic efficiency. Therefore, Ag-TiO2/rGO, as a potential anode material, exhibits a superior stability property for long-life LIBs and also builds up a pathway for further studies on fabrication of ternary nanomaterials for electrochemical energy storage applications.
