Title: Methods of preparing composite carbon-graphite-silicon particles and using same

Abstract: A process for production of coated silicon-carbon composite particles includes providing a carbon residue-forming material, providing particles of a carbonaceous material, and coating in a liquid suspension mixture the particles of carbonaceous material with the carbon residue-forming material to form coated carbonaceous particles. Providing silicon particles added to the mixture, coating the silicon particles embedded on the coated carbonaceous particles to form silicon-carbon composite particle. Some embodiments utilize the composite particle in an anode of a battery.
