▎ 摘　　要

NOVELTY - An antimony pentoxide/graphene oxide/carbon cloth electrode material is prepared by immersing carbon cloth in acetone, taking out, washing, drying, anodizing, washing, drying, adding 3-10 mg graphene oxide and 0.3-1.0 g antimony trichloride in 20-60 mL absolute ethanol, dissolving to obtain hydrazine solution, adjusting pH value to 8-12 using sodium hydroxide aqueous solution, adding anodized carbon cloth, carrying out hydrothermal reaction at 150-180 degrees C, cooling, taking out carbon cloth, washing, and drying. USE - A method for preparing antimony pentoxide/graphene oxide/carbon cloth electrode material for carbon cloth-based flexible sodium ion battery anion (claimed). ADVANTAGE - The product exhibits excellent electrochemical cycle performance, has simple preparation, has short preparation cycle, high repeatability, and is suitable for industrialization.
