Despite its high theoretical specific capacity, direct application of SiO${}_x$ is challenging particularly in terms of alleviating volume effect and improving electronic conductivity to enhance the battery performance. SiO${}_x$/CNTs/Sn composite with high cyclability and rate performance was proposed by a modified Stöber liquid phase method, CNTs and metallic tin were employed during the subsequent mechanical ball milling process to investigate their effects on the resulting physicochemical property and electrochemical performance. The structure of/CNTs/Sn composite was designed, and the multi-structure not only alleviates the volume effect of SiO${}_x$ to a certain extent but also provides additional diffusion pathways for lithium ions, electrons, and flexible substrate. From electrochemical characterization, the half-cell battery integrating SiO${}_x$/CNTs/Sn anode exhibits a capacity of 880.83 mAh g${}^{-1}$ with 6.3% capacity fading after 100 cycles at 0.1 A g${}^{-1}$ and excellent rate performance. The simple and ingenious synthesis method could provide new development and application ideas for SiO${}_x$-based anode materials.
