| Abstract: |
| The closed-loop recovery process of selective recovery of Li and Ni, Co, Mn and reuse was achieved by carbon thermal reduction, water leaching, and high temperature solid phase roasting applying waste ternary lithium battery cathode material as the research object. Li leaching rate is 91.04% under the optimal conditions including roasting temperature of 650 ℃, roasting time of 2 h, carbon addition of 10%, leaching time of 1 h, and solid-liquid ratio of 30 g/L. The leaching solution can be recycled three times to increase the Li concentration from 1.01 g/L to 2.68 g/L. Li2CO3 is prepared by evaporation crystallization of the leaching solution. The leaching residue which mainly composed of Ni, Co, and MnO, is roasted in air atmosphere to prepare a ternary precursor. Then Li2CO3 and ternary precursors are mixed and grinded for roasting to obtain a regenerated ternary material. |
