| Use advice for data set | When using this LFP battery hydrometallurgy dataset, users should account for the variation in metal recovery rates due to different conditions and technologies cited in multiple papers. The dataset's functional unit is 1 kWh, which requires users to adjust their calculations based on the capacity of the batteries studied. Users must consider the technological applicability of the data, specifically related to the efficiency and purity of the recovered materials, to ensure its relevance for their specific recycling processes or life cycle assessments. |
| Technical purpose of product or process | The hydrometallurgical process described is utilized for the recovery and recycling of valuable metals from end-of-life (EoL) lithium iron phosphate (LFP) batteries. It involves disassembly, crushing of spent batteries, extraction of metals via leaching in an acid-base solution, followed by purification processes to obtain high-purity lithium iron phosphate (LiFePO4). This recycled LiFePO4 can be used as a cathode material for the manufacturing of new lithium-ion batteries. |

| Technology description including background system | The waste LFP that have been identified as containing iron and lithium need to be discharged first, dried naturally, and then heat treated to remove the diaphragm, electrolyte, binder, etc., and then separated copper and aluminum by multi-stage crushing. For steel shell batteries or soft pack batteries, stainless steel or aluminum-plastic films, diaphragms, etc. The remaining positive and negative electrode materials are extracted by leaching, precipitation, impurity removal, extraction and purification to obtain lithium carbonate, lithium phosphate, lithium chloride, etc. The iron and phosphorus slag and carbon slag produced in the process are recovered as by-products. Recycled lithium carbonate, lithium phosphate, lithium chloride and lithium hydroxide are used as raw materials for lithium battery production, and by-product iron phosphorus residue can be synthesized again into iron phosphate products, or recycled to obtain iron hydroxide and phosphoric acid raw materials. |
