Restricted-magnesium-vapor-reduction of amorphous SiO/C precursors to polycrystalline Si/SiO/C hybrid anodes

Considering the electrochemical activity/stability and preparation feasibility of silicon (Si) nanomaterials, we designed a restricted-magnesium-vapor-reduction to fabricate sustainable Si/SiO x /C porous anodes with nanopores and polycrystalline structures. A method that combines disproportionation and magnesium-vapor-reduction in one step, which is different from traditional magnesium thermal reduction, was designed for synthesizing advanced silicon-based anode materials.
