▎ 摘　　要

NOVELTY - The method comprises (1) measuring graphene oxide solution, adding to distilled water, ethanol or a mixture of water and ethanol, stirring at room temperature or ultrasonically processing, (2) adding cetyltrimethylammonium bromide (CTAB) or tetradecyltrimethylammonium bromide (TTAB) or octadecyltrimethylammonium bromide (STAB) to oxidation in graphene dispersion solution, magnetically or mechanically stirring at room temperature, (3) adding sodium molybdate or ammonium molybdate and L-cysteine or thiourea into mixed I solution, magnetically or mechanically stirring at room temperature, (4) transferring mixed II solution into hydrothermal reactor, and reacting, (5) filtering or centrifugal washing to clean with ethanol, acetone, and/or water, and drying, (6) adding the dried powder in a tube furnace, heat treatment in gas flow in atmosphere of nitrogen or argon or first mixed gas of nitrogen and argon, and cooling, and (7) performing nitrogen doping on the composite material. USE - Method for preparing three-dimensional nitrogen-doped graphene/molybdenum disulfide long cycle life zinc air battery material, which is useful as energy conversion device of the battery. ADVANTAGE - The battery material has long cycle life, and has wide application prospect in the field of zinc air battery as new energy material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a three-dimensional nitrogen-doped graphene/molybdenum disulfide long cycle life zinc-air battery material.
