| titleOfInvention | A kind of wet surface treatment method of high nickel cathode material, obtained material and application |
| abstract | The invention discloses a wet surface treatment method for a high-nickel positive electrode material, the obtained material and application, and belongs to the technical field of lithium battery materials. The wet surface treatment method of the high-nickel positive electrode material includes: using a strong oxidizing gas to cyclically purge the water-containing high-nickel positive electrode material after water washing and pressure filtration, so as to reduce the residual alkali on the surface of the high-nickel positive electrode material, wherein the strong oxidizing gas It is one or more of ClO 2 , Cl 2 , Cl 2 O and Cl 2 O 7 , and the amount of the strong oxidizing gas is 0.1%-0.5% of the total mass of the high-nickel cathode material. For example, the strong oxidizing gas ClO 2 gas is passed into the water-containing material after washing and pressure filtration, so that it reacts with the residual alkali remaining in the water on the surface of the pressure filter material to generate lithium chlorite and chloric acid that are more soluble in water. Lithium is more conducive to be taken away during the purging process, even if the lithium chlorite and lithium chlorate remaining in the material do not increase the residual alkali value of the material, the residual alkali value of the material is significantly reduced. |
