| titleOfInvention | Method for preparing lithium-rich solid solution cathode material through gas oxidation and acid solution combined treatment |
| abstract | The invention relates to a method for preparing a lithium-rich solid solution cathode material through gas oxidation and acid solution combined treatment. The method comprises the following steps of: weighing a lithium compound, a nickel compound, a manganese compound and a cobalt compound in a molar ratio of lithium ions to nickel ions to manganese ions to cobalt ions of (1+x):(1-x).y:(x+z-x.z):(1-x).k; mixing the weighed nickel compound, manganese compound and cobalt compound in a wet grinding medium, performing wet grinding and mixing, adding ammonia water and the lithium compound, performing wet grinding and mixing again, aging a reaction mixed solution containing a precipitate, heating, drying, putting a precursor 2 in air, oxygen-rich gas or pure oxygen atmosphere, and performing two-section sintering to prepare a precursor 3; and treating the precursor 3 by using an acid solution, drying, and sintering to obtain the lithium-rich solid solution cathode material. The electrode material prepared by the method has uniform composition, high discharge performance, and high charge and discharge current efficiency particularly under the high-current condition. |
