| titleOfInvention | A kind of method for preparing battery grade nickel cobalt manganese |
| abstract | The invention provides a method for preparing battery grade nickel cobalt manganese. The method includes the following steps: (1) pre-separating and extracting the leachate containing the positive electrode powder to obtain an aqueous phase 1 and an organic phase 1, washing and back-extracting the organic phase 1 to obtain a back-extracting solution 1; (2) extracting the step (1) the obtained aqueous phase 1 is extracted and separated to obtain an aqueous phase 2 and an organic phase 2; (3) the back-extraction liquid 1 obtained in step (1) and the organic phase 2 obtained in step (2) are subjected to extraction and separation to obtain water Phase 3 and organic phase 3, the organic phase 3 is washed and back-extracted to obtain a solution containing iron, aluminum, zinc and copper. By the method provided by the invention, the nickel, cobalt and manganese in the battery feed liquid containing nickel, cobalt and manganese can be extracted synchronously. Recycling, compared with the existing process, the process is short and the cost is low, and the battery-grade nickel-cobalt-manganese can be directly prepared. |
