Abstract
A method of producing an anode material for a lithium-ion battery includes combining an electrode precursor material and humic acid in an alkaline slurry, drying the alkaline slurry to produce a powder of humic acid-coated electrode precursor material, and heating the powder to produce the electrode material comprising graphene-coated particles.
