| titleOfInvention | Preparation method of cubic carbon-coated vanadium-based positive electrode material |
| abstract | The invention provides a preparation method of a cubic carbon-coated vanadium-based positive electrode material, which comprises the following steps: dissolving a vanadium source in deionized water, heating and stirring until the vanadium source is completely dissolved, and adding a lithium source and a phosphorus source or adding a sodium source and a phosphorus source to form a first mixture; stirring the first mixture until the first mixture is dissolved, adding a reducing agent and a morphology directing agent, heating, stirring and dissolving to obtain a second mixture; reacting the second mixture at 150-300 ℃ for 7-25 h, cooling, washing brown precipitate with deionized water and absolute ethyl alcohol, drying, and grinding to obtain precursor powder; heating the precursor powder to 250-450 ℃ under the inert gas atmosphere, heating at a constant temperature for 3-5 h, cooling, and grinding to obtain pre-sintered powder; and heating the pre-sintered powder to 700-1000 ℃ under the inert gas atmosphere, calcining at a constant temperature for 5-30 h, cooling, grinding and sieving to obtain the carbon-coated vanadium-based composite anode material with the cubic morphology. |
