(229m) Silicon@Carbon Nanomaterials Application in Anode for Li-Ion Batteries

a core–shell structured Silicon@Carbon nanocomposite was prepared by using a simply Stöber method assisted approach. Stöber method was firstly introduced to synchronously synthesize uniform Monodisperse SiO₂@Resorcinol–Formaldehyde Resin and tetraethoxysilane (TEOS), resorcinol and formaldehyde were used starting materials. And then an easier magnesiothermic reduction technique was selected to promote the development of Silicon@Carbon nanocomposite. Moreover, we can obtain Yolk-shell/Hollow-shell Silicon@Carbon nanostructures from the SiO₂@ Resorcinol–Formaldehyde Resin by modified the preparation procedure.  As an anode material in Li-ion batteries, these Silicon@Carbon core-shell nanomaterials show highly stable and high capacity retention rate, which suggest that the novel hybrid materials have alluring prospect for electrochemical energy storage applications.
