摘要

Abstract

Micro/nanostructured SiO

/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

component. The micron-sized SiO x/C spheres are composed of many near-spherical nanoparticles. The synthesized SiO

/C exhibits a stable and high reversible capacity of 830 mA·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 SiO

component combinedly contribute the excellent electrochemical performance.
