1. A method of fabricating a battery anode electrode composition comprising a plurality of composite particles, each particle in the plurality of composite particles comprising a porous carbon particle and an electrochemical modifier incorporated into the pores of the porous carbon particle by the method comprising:

a. forming the porous carbon particle by:

i. pyrolyzing a polymer to form a carbon particle;

ii. activating the carbon particle to form an activated carbon particle; and

iii. performing a particle size reduction of the activated carbon particle to form the porous carbon particle; and

b. introducing the electrochemical modifier into the pores of the porous carbon particle through the vapor phase to form the composite particle,

wherein:

the polymer is formed from a polymer precursor; and

the polymer precursor comprises a saccharide, a protein, a biopolymer, or a combination thereof.
