1. A method of forming carbon-coated anode particles, the method comprising:
mixing a first plurality of particles, a second plurality of particles, and a plurality of graphene particles to form a dry powder, the first plurality of particles including at least one of particles rejected from a graphite spheronization process or silicon particles, the second plurality of particles comprising graphite particles including particles rejected from a graphite micronization process;
mixing the dry powder with water and a carbon-containing liquid to form a slurry;
spray-drying the slurry to form an agglomerated mix; and
heating the agglomerated mix to form carbon-coated anode particles.
