▎ 摘　　要

NOVELTY - Preparing antimony sulfide/graphene composite nano material comprises (1) ultrasonically dispersing graphene in water, adding a mixed aqueous solution of antimony salt and inorganic acid, and mixing well; and (2) adding an aqueous solution of sulfur source to the mixed solution obtained in step (1), uniformly mixing, ultrasonically reacting, washing and drying to obtain product. USE - The composite nano material is useful in the cathode material of battery (claimed). ADVANTAGE - The method: can quickly and stably prepare uniform antimony sulfide/graphene composite nano material under normal temperature conditions through a simple and easy ultrasonic synthesis; and is simple. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the antimony sulfide/graphene composite nano material is prepared by above mentioned method.
