▎ 摘  要

NOVELTY - An anode material of aqueous zinc ion battery is prepared by dissolving manganese source in water, adding oxidant and sulfur, uniformly stirring, transferring to hydrothermal reaction kettle to carry out hydrothermal reaction to obtain precipitate, uniformly stirring precipitate and organic additive solution, spray drying to obtain precursor, calcining in muffle furnace at 300-1000degrees Celsius to obtain manganese oxide/sulfur precursor material, ultrasonically assisting to disperse precursor material and carbon source in water to obtain dispersion liquid, drying, and calcining in tubular furnace under inert gas atmosphere at 300-800degrees Celsius. USE - The method is used for preparing anode material of aqueous zinc ion battery. ADVANTAGE - The material has good appearance structure, large specific surface area and good conductivity. The battery has high specific capacity and excellent cycle stability.
