1. A method of forming an anode of a battery, the method comprising:
mixing a composition comprising a silicon-based active material, a carbon-based binder, and a carbon-based additive, wherein onset of pyrolysis of the composition starts at an onset pyrolysis temperature;
coating a conductive foil with the composition; and
subjecting the coated conductive foil to a pyrolysis process at a temperature less than 600° C. and greater than the onset pyrolysis temperature of the composition, wherein the pyrolysis process pyrolyzes the composition coated on the conductive foil resulting in the anode comprising the conductive foil and an active material layer of the pyrolyzed composition on the conductive foil.
