▎ 摘 要
NOVELTY - Preparing graphene antimony nanotube cathode material involves making certain mole amount of sodium sulfide and dissolving in glycol to obtain first precursor solution, making certain mole of antimony chloride and dissolving in glycol to obtain second precursor solution, adding first precursor solution with stirring in second precursor solution to obtain third solution, where molar ratio of sodium sulfide and antimony is 1-3:3, dispersing certain concentration of graphene dispersion into third solution, and transferring to polytetrafluoroethylene liner at high pressure kettle at 120 degrees C and keeping for 3 hours to obtain synthesis product, separating solvent thermal synthesis product through 10000 revolutions/minute, washing with de-ionized water and ethanol, drying at 85 degrees C to obtain fifth product, reacting obtained product for 12 hours and mixing with hydrogen and argon gas atmosphere, annealing at 350 degrees C for 12 hours to obtain graphene antimony nano-composite. USE - Method for preparing graphene antimony nanotube cathode material for sodium ion battery. ADVANTAGE - The method enables to prepare graphene antimony nanotube cathode material has high recycle ratio capacity, coulombic efficiency and stable cycle performance.
