Molybdenum-fluorine-doped $ SnO_{2} $ nanoparticles based on 3D interconnected carbon structure as matrix as high-performance lithium-ion anode material

Abstract The preparation of nanostructured anode materials which can adapt to lithiation strain with higher structural stability and specific capacity is the primary challenge for the development of lithium-ion batteries (LIBs). Herein, we developed a carbon-coated, fluorine-molybdenum-doped $ SnO_{2} $ ($ SnO_{2} $C-$ MoF_{4} $) green composite with high long-term cycling stability and specific capacity. The composite materials were prepared by the NaCl template method. The carbonaceous composites prepared by the NaCl template method will form a three-dimensional (3D) interconnected carbon structure, which can well alleviate the problem of the large volume change of $ SnO_{2} $ during the lithium intercalation/delithiation process. Thereby, under the premise of maintaining a higher specific capacity, it can improve the long-term cycling stability of tin-based lithium-ion battery anode materials to meet the requirements of high-performance lithium-ion battery anode materials. The $ SnO_{2} $@C-$ MoF_{4} $ composites prepared by the template method have an outstanding specific capacity (845.10 mAh/g) at 0.2 A/g, and superior cycling stability (749.19 mAh/g) was obtained after 800 charge–discharge cycles at 1.0 A/g..
