| titleOfInvention | Preparation method of aluminum oxide and carbon composite coated sodium vanadium fluorophosphate cathode material |
| abstract | The invention provides an alumina and carbon composite coated sodium vanadium fluorophosphate cathode material and a preparation method thereof, wherein oxalic acid H is used 2 C 2 O 4 Dissolving sodium fluoride NaF, a vanadium source and a phosphorus source in deionized water, stirring at 60 ℃ to form gel, drying, and presintering the powder in a tube furnace to obtain a precursor; adding a carbon source into the precursor, performing ball milling, drying, calcining in a tubular furnace under the nitrogen atmosphere, and sieving to obtain a carbon-coated sodium vanadium fluorophosphate cathode material; ultrasonically dispersing carbon-coated sodium vanadium fluorophosphate in deionized water uniformly, and adding aluminum nitrate Al (NO) nonahydrate 3 ) 3 ·9H 2 O ultrasonic treatment for 20 min, stirring for 30 min, and adding ammonia NH 3 ·H 2 And O, continuously stirring for 1.5 hours at the temperature of 60 ℃, then carrying out suction filtration, washing for multiple times by using deionized water, drying, finally carrying out final firing in a tubular furnace, cooling, and sieving to obtain the aluminum oxide and carbon composite coated sodium vanadium fluorophosphate cathode material. |
