SiO/C Composite Materials for Lithium-Ion Secondary Batteries

Article Preview

Abstract:

The SiO/C composite materials were prepared via a solution route and subsequent thermal treatment. The effects of carbon source on the particle morphology of composite, the graphitization degree of carbon component and the electrochemical performance of the prepared SiO/C composites were investigated by scanning electron microscopy (SEM), Raman spectrometer and electrochemical charge/discharge tests. The results reveal that the SiO/C composite synthesized with the epoxy resin as carbon source exhibits the higher graphitic degree and higher reversible specific capacity (~690 mAhg-1) and excellent cycling stability.
