DETAILED DESCRIPTION - An anode material comprises sodium nickel-metal oxide and 1-10 wt.% conductive carbon and has a specific area of 0.3-1.2 m2/g and D50 particle diameter of 5-30 nm. The conductive carbon comprises at least one of graphene, carbon nanotube, conductive carbon black, and acetylene black. The sodium nickel-metal oxide is of formula: NaxNiyM1-yO2, where x is 0.5-1, y is 0.1-0.5 and M is at least one of manganese, iron, zinc, silver, zirconium, vanadium, molybdenum, niobium, copper, chromium, and titanium. An INDEPENDENT CLAIM is included for the preparation of anode material which involves (1) mixing a sodium salt, nickel salt, (M) salt, conductive carbon, and a solvent to form a mixed slurry, (2) atomizing and directly calcining.
