| Use advice for data set | When utilizing this data set related to the NCM 622 battery recycling process, it is essential to contextually include this recycling loop in Life Cycle Assessments (LCA) for electric vehicles where the functional unit is 1 kWh of the NCM 622 battery pack. Users should note that data derives from field research, and assumptions about the purity of recovered materials and the efficiency of the recycling process should be carefully considered. It is also important to consider the exclusion of primary material production impacts where applicable. |
| Technical purpose of product or process | The NCM 622 hydrometallurgical recycling process is intended for the recovery of materials from spent lithium-ion batteries (LIBs). It is particularly suitable for recycling used NCM 622 batteries from battery electric vehicles (BEVs) to reintegrate into the production of NCM 622 cathode materials, thus mitigating the need for extraction and production of virgin raw materials like steel, aluminum, polypropylene, and copper. |

| General comment on data set | In hydrometallurgy the materials in LIBs are selectively dissolved by chemical solvents and the metal elements are separated in the leachate. The used NCM 622 batteries are 100% collected and recycled by hydrometallurgical methods to feed into NCM 622 production loop and thus avoid the production of primary materials, such as steel, aluminum, polypropylene and copper. |
