Abstract	Micro/nanostructured SiO_x/C composite was firstly synthesized by carbothermal reduction of silica-carbon binary xerogel. The homogeneous dispersion feature of the two components in binary xerogel contributes to effectively carbothermally reduce the O/Si atomic ratio, enhancing the electrochemical activity of the SiO_x component. Themicron-sized SiO_x/C spheres are composed of many near-spherical nanoparticles. The synthesized SiO_x/C exhibits a stable and high reversible capacity of 830mA·h·g~(–1) for 100 cycles, and excellent rate-capability. The homogeneous dispersion structure of phases, the micro/nanostructure and the high electrochemical activity of SiOx component combinedly contribute the excellent electrochemical performance.
