Abstract

Embodiments provide a method of producing micro-sized Si—C composites or doped Si—C and Si alloy-C with interconnected nanoscle Si and C building blocks through converting commercially available SiOx (0<x<2) to a silicon framework by calcination, followed by etching and then by carbon filling by thermal deposition of gas containing organic molecules that have carbon atoms.
