NOVELTY - An anode material comprises cobalt single atom nitrogen-doped graphene. USE - The anode material is used for aluminum-sulfur battery (claimed). ADVANTAGE - The method is simple. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the anode material comprising dissolving cobalt salt in deionized water, stirring, and dissolving to prepare cobalt salt solution with concentration of 1-6 mg/mL; ultrasonically dispersing a certain amount of graphene oxide in the deionized water, adding cobalt salt, and mixing; freeze-drying, drying e material under a certain gas atmosphere, reacting for 2-6 hours at 600-900 degrees C, and naturally cooling to room temperature; and washing and drying the reacted sample.
