| Use advice for data set | When utilizing this lifecycle assessment data, users should ensure that the methodological boundaries correspond to their specific application. Pay attention to the functional unit of 1 kWh as the reference basis for energy content comparison. This data is sourced from multiple papers, so practitioners must ensure consistency and relevance to their context. Exclusion of steps not applicable to the specific recycling process in question, such as processes for different battery chemistries, may be needed, and users should account for technological variations and regional practices in their assessments. |
| Technical purpose of product or process | The described hydrometallurgy process for ternary lithium batteries is used for the recycling and recovery of valuable metals from end-of-life (EoL) NCM (nickel, cobalt, manganese) cathode materials. Specifically, this process enables the extraction and purification of Li(NixCoyMn1-x-y)O2 compounds, which are vital for manufacturing new lithium-ion batteries or for other industrial applications requiring high-grade metal oxides. |

| General comment on data set | First, the EoL LFP batteries were disassembled and crushed. The processed battery material was then dissolved in an acid-base solution to extract some of the valuable metal elements. Finally, decontamination and purification were performed to obtain Li(NixCoyMn1-x-y)O2. |
