1-54. (canceled)
A method of fabricating a battery anode electrode composition comprising a plurality of composite particles, the method comprising:
- pyrolyzing a polymer to form a carbon particle;
- activating the carbon particle to form an activated carbon particle;
- and
- performing a particle size reduction of the activated carbon particle to form porous carbon particles;
- and
- introducing the electrochemical modifier into pores of the porous carbon particles through the vapor phase to form the plurality of composite particles.
A method of fabricating a battery anode electrode composition comprising silicon-carbon composite particles, the method comprising:
- polymerizing one or more polymer precursors to form a polymer particle having pores;
- pyrolyzing the polymer particle to form a carbon particle having pores;
- activating the carbon particle to form an activated carbon particle;
- performing a particle size reduction of the activated carbon particle to form the porous carbon particles;
- and
- introducing the porous carbon particles to an electrochemical modifier comprising elemental silicon incorporated within the pores of the porous carbon particles to form the silicon-carbon composite particles.
