Embodiment 1
[0050] Add 2.0913g of ammonium dihydrogen phosphate and 5.188g of oleic acid into a 50ml stainless steel ball mill jar, add 20 304 stainless steel balls each with a diameter of 2mm and 4mm as the ball milling medium, and use a high-energy mechanical ball mill to mix for 3 hours to obtain milky white mixture. 10.376 g of paraffin wax was added, followed by ball milling for 2 hours. Then 2.184 g of vanadium oxalate was added, and ball milling was continued for 2 hours to obtain a viscous mixture. Finally, 1.566 g of anhydrous sodium acetate was added and ball milled for 3 hours to obtain a solid or semi-liquid sodium vanadium phosphate precursor. Turn the sodium vanadium phosphate precursor to a H 2 1Ar (Ar and H 2 In a quartz tube furnace with a volume ratio of 95:5) mixed gases, the heating rate was raised to 800°C for 8h at a heating rate of 2°C for 1min, and the furnace was cooled to obtain a graphene-like carbon-coated sodium vanadium phosphate material. The crystal str...
