| titleOfInvention | Method for directly preparing lithium zincate modified ternary cathode material by using waste lithium battery cathode material |
| abstract | The invention belongs to the technical field of ternary material precursor preparation, and particularly relates to a method for directly preparing a lithium zincate modified ternary positive electrode material by using a waste lithium battery positive electrode material, which comprises the following steps: separating the anode material from the waste lithium ion battery; leaching with caustic solution, and filtering; adding carbonate into the filtrate to obtain lithium carbonate; leaching the filter cake with sulfuric acid to obtain a leaching solution; adjusting the mole ratio of nickel, cobalt and manganese in the leaching solution; enabling the leachate, an ammonia water solution and a caustic alkali solution to flow into a reaction kettle in parallel, and preparing a ternary material precursor through coprecipitation; mixing the lithium carbonate with the mixture and roasting the mixture to obtain a ternary cathode material; mixing zinc acetate, glycol ether, amine and lithium methoxide, adding the ternary cathode material to obtain gel, and roasting to obtain the lithium zincate modified ternary cathode material. The lithium zincate modified ternary cathode material has the advantages of strong structural stability, good electrochemical performance, reduced production cost, high product quality and realization of directional circulation of nickel, cobalt, manganese and lithium resources. |
