▎ 摘　　要

NOVELTY - Preparing graphene oxide/sulfide composite electrode material comprises dissolving graphite oxide with deionized water, ultrasonically peeling off to obtain oxidized graphene solution, adding dimethylformamide, acid salt, and water reducing agent, dispersing uniformly to prepare the mixed solution to a reaction kettle, centrifuging at less than or equal to 180 degrees C, heat preservation for 5-10 hours, removing dimethyl formamide by washing with deionized water, and drying by spraying continuously to obtain the composite electrode material. USE - Method for preparing graphene oxide/sulfide composite electrode material. ADVANTAGE - The method is simple and suitable for industrial large-scale production, and has low production cost and good electrochemical performance.
