| Abstract: |
| With rapid development of new energy vehicles, a large number of waste batteries will be generated after retirement of LiFePO4 power batteries. It will pollute environment and waste metal resources if they are not disposed of in time. Recycling technology progress of spent LiFePO4 cathode materials in recent years was introduced, including hydrometallurgical recovery of valuable metals, repair and regeneration of spent LiFePO4 and decomposition and resynthesis of LiFePO4, etc. Advantages and disadvantages of different recycling methods were pointed out. Development direction of spent LiFePO4 batteries recycling technology was prospected. |
