NOVELTY - Preparing nano antimony/graphene composite material comprises mixing antimony oxide, graphene oxide and reducing agent through mechanical grinding to obtain antimony oxide/graphene oxide/reducing agent mixture, heating at 200-600°C for 1-10 hours to obtain the precursor product, and washing the precursor product with water and drying to obtain the nano-antimony/graphene composite material. USE - The method is useful for preparing nano antimony/graphene composite material. ADVANTAGE - The method is simple, has mild condition, economical, is not good for commercial use in large scale. The prepared nano antimony/graphene composite material as sodium ion battery material cathode exhibits excellent cycle stability.
