| Abstract: | Based on a summary of the existing recovery technologies for spent LiFePO4, a brief introduction of repair and regeneration technologies for spent LiFePO4 cathode material is presented. The technical theory for selectively leaching spent LiFePO4 by hydrometallurgical approach, as well as the progress in the research of the existing technical schemes are specifically reviewed, and some new recovery techniques are also briefly introduced. Based on the comparison of the advantages and disadvantages of different technical schemes, the technical development trend for lithium recovery from spent LiFePO4 batteries is predicted. |
