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. 经鉴别为含铁元素、锂元素的废旧磷酸铁锂电池需要先放电处理、自然干燥，然后进行热处理，去除隔膜、电解液、粘结剂等，再通过多级破碎分选铜、铝，对于钢壳电池或软包电池再分选出不锈钢或铝塑膜、隔膜等，剩余的正负极材料经浸出、沉淀除杂、萃取提纯得到碳酸锂、磷酸锂、氯化锂等，过程中产生的铁磷渣、碳渣作为副产品回收;回收得到的碳酸锂、磷酸锂、氯化锂和氢氧化锂用于锂电池生产的原料，副产品铁磷渣可以再次合成磷酸铁产品，或者回收得到氢氧化铁和磷酸原料。 The hydrometallurgical process described is utilized for the recovery and recycling of valuable metals from end-of-life (EoL) lithium iron phosphate (LFP) batteries.

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. 使用该LFP电池湿法冶金数据集时，用户应考虑由于引用多篇论文中不同的条件和技术所致的金属回收率的变化。数据集的功能单位是1 kWh，这要求用户根据所研究电池的容量调整他们的计算。用户必须考虑数据的技术适用性，特别是与回收材料的效率和纯度相关，以确保其对他们特定的回收过程或生命周期评估的相关性。 Inventory: The internal review was done by several iteration steps concerning raw data validation, raw data documentation, representativity, completeness and consistency of modelling with regard to ISO 14040 and 14044. 清单： 内部审查通过几个迭代步骤完成，涉及原始数据验证、原始数据记录、代表性、完整性、与 ISO 14040 和 14044 有关的建模的一致性。 Tiangong LCI Data Working Group 天工LCI数据工作小组 Pengfei, pengfei24@email.ncu.edu.cn 彭菲, pengfei24@email.ncu.edu.cn pengfei24@email.ncu.edu.cn pengfei24@email.ncu.edu.cn 2024-04-11T15:54:21+08:00 2024-04-20T14:28:25.258991+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=8d8cfd57-7be0-4c12-96ad-07fff1911ddd&version=01.00.000&stock=TianGong Tiangong LCI Data Working Group 天工LCI数据工作小组 false Free of charge for all users and uses Lithium carbonate Input 0.23 0.23 Lithium carbonate, production mix/CN 碳酸锂，生产混合物/CN Sulphuric acid Input 9.54 9.54 Sulphuric acid, production mix/EU-28 硫酸，生产混合物/EU-28 sodium hydroxide Input 5.79 5.79 Sodium hydroxide, production mix/EU-28 氢氧化钠，生产混合物/EU-28 Hydrogen peroxide (30%) Input 3.25 3.25 Hydrogen peroxide 过氧化氢 Electricity Input 11.8 11.8 natural gas,natural gas Input 6.24 6.24 carbon monoxide (fossil) Output 0.18 0.18 aluminium Output 0.14 0.14 copper Output 0.038 0.038 Lithium Iron Phosphate (LiFePO4) Output 2.58 2.58 EoL LFP battery Input 3.6 3.6
