| titleOfInvention | A carbon-coated LiVPO4F cathode material and its preparation and application |
| abstract | The invention discloses a preparation method of a carbon-coated LiVPO 4 F positive electrode material. Add oxalic acid, citric acid or ascorbic acid to deionized water to form a transparent solution, and then add vanadium source, lithium source, phosphorus source and fluorine source in a molar ratio of 1:1:1:1 at a temperature of 20-90℃. Mix evenly in the solution, react for 1-12h to form a colloidal solution, dry at 70-140°C for 6-48h to obtain a solid product, heat the dried solid product at 300-500°C for 1-12h in an inert atmosphere An intermediate product is obtained; then the intermediate product is mixed with 5%-100% of the mass of the intermediate product and ball-milled with a fluoropolymer (PTFE, PVDF or PCTFE) for 1-24h, and then sintered at 500-800°C for 1-12h in an inert atmosphere A pure phase LiVPO 4 F/C cathode material was obtained. The carbon-coated LiVPO 4 F material prepared by the invention has high crystal phase purity, and the introduction of fluorine-containing polymer not only effectively improves the crystal phase purity of the material as an additional fluorine source, but also coats the surface of LiVPO 4 F as a carbon source, Improve the electronic conductivity of the material, resulting in excellent electrochemical performance. |
