Title: Synthesis of micro-sized interconnected Si-C composites

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 SiO.sub.x (0<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.
