▎ 摘 要
NOVELTY - Preparation of hexavanadium tridecoxide/reduced graphene oxide composite material zinc ion battery anode material comprises mixing vanadium source, reducing agent and deionized water, vigorously stirring for 2-6 hours at 20-50 degrees C, transferring to high pressure kettle, reacting at 150-200 degrees C for 24-48 hours, centrifuging, washing with deionized water and ethanol, and vacuum drying at 60-70 degrees C for 12-16 hours; calcining under argon gas atmosphere at 250-350 degrees C for 12 hours, naturally cooling to room temperature, and grinding; adding graphene oxide into deionized water, ultrasonically dispersing for 2-6 hours, adding second step product, stirring for 3-6 hours, and freeze-drying; calcining under argon gas atmosphere to 500 degrees C for 4 hours, cooling to room temperature, and grinding; and mixing conductive agent and binder at mass ratio of 8:1:1, adding N-methylpyrrolidone, ball milling for 4 hours, coating slurry on stainless steel foil, and vacuum drying for 10-12 hours at 100-120 degrees C. USE - The method is used for preparation of hexavanadium tridecoxide/reduced graphene oxide composite material zinc ion battery anode material (claimed). ADVANTAGE - The composite material has short preparation time, low cost, simple preparation method, high coulomb efficiency and cycle stability, and large specific surface area, is good for removing and embedding zinc ion, has good electrochemical zinc storage performance, and can be used as large energy storage tool to effectively store and distribute energy.
