Claim:
1. A method for making a silicon-based active electrode material, the method comprising: introducing a silicon active material precursor to a carrier gas; prior to, simultaneously with, or subsequent to the introduction of the silicon active material precursor to the carrier gas, introducing a graphene active material precursor to the carrier gas; prior to, simultaneously with, or subsequent to the introduction of the silicon active material precursor to the carrier gas, introducing an other active material precursor to the carrier gas, the other active material precursor being selected from a group consisting of a tin active material precursor, an aluminum active material precursor, and combinations thereof; and exposing the carrier gas containing any of the silicon active material precursor, the graphene active material precursor, the other active material precursor, or combinations thereof to plasma vaporization, thereby forming a material including a graphene layer having an alloy of phase separated i) silicon and ii) tin, aluminum, or tin and aluminum deposited on a surface thereof.
