| titleOfInvention | Method for preparing lithium-rich solid solution cathode material through reduction |
| abstract | The invention relates to a method for preparing a lithium-rich solid solution cathode material through reduction. The method is characterized by comprising the following steps of: weighing a lithium compound, a nickel compound, a manganese compound, a cobalt compound and a reducing agent in a molar ratio of lithium ions to nickel ions to manganese ions to cobalt ions to the reducing agent of (1+x):(1-x).y:(x+z-x.z):(1-x).k:q; and mixing the reducing agent and a wet grinding medium, mixing the weighed nickel compound, manganese compound and cobalt compound in a mixture, performing wet grinding and mixing, adding ammonia water, performing wet grinding again, aging, drying, putting a precursor in air, oxygen-rich gas or pure oxygen atmosphere, and performing two-section or two-time sectional sintering to prepare the lithium-rich solid solution cathode material xLi2MnO3.(1-x)Li[NiyMnzCok]O2. The electrode material prepared by the method has uniform composition, high discharge performance, and high discharge cycle performance particularly under the high-current condition. |
