A method for forming an anode of a sodium ion battery includes a step of heat treating the red phosphorus precursor and reduced graphene oxide powder at a first temperature that vaporizes the red phosphorus precursor such that red phosphorus structures grow on the reduced graphene oxide powder. Another method for forming an anode of a sodium ion battery includes steps of placing a red phosphorus precursor and a graphene oxide precursor in a reaction chamber; establishing a reducing environment in the reaction chamber; and heating the red phosphorus precursor and a graphene oxide precursor to a first temperature that is sufficient temperature to form a composite of red phosphorus and reduced graphene oxide. Characteristically, red phosphorus deposition and graphene oxide reduction are completed simultaneously in a single-step heat treatment. A method for making a black phosphorus-composite for sodium-ion batter anodes is also provided.
