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. 在湿法冶金中，LIB 中的材料被化学溶剂选择性地溶解，金属元素从浸出液中分离出来。使用过的 NCM 622 电池可通过湿法冶金方法进行 100% 的收集和回收，并进入 NCM 622 的生产循环，从而避免生产钢、铝、聚丙烯和铜等初级材料。 The functional unit is defined as 1 kWh of the NCM 622 pack for a passenger BEV. 0 2020 In hydrometallurgy the materials in LIBs are selectively dissolved by chemical solvents and the metal elements are separated in the leachate.

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. 三元锂电池湿法冶金回收过程专为从废旧锂离子电池（LIBs）中回收材料而设计。特别适用于从电动汽车（BEVs）中回收使用过的NCM 622电池，以重整到NCM 622阳极材料的生产中，从而减轻对钢铁、铝、聚丙烯和铜等原生原材料的提取和生产需求。 LzWibtrltoqtU5xW4PpcNqDnnyc.png Unit process, single operation None 无 None 无 None 无 Data from field research. 数据来源于实地调研。 None 无 None 无 Sun,X., Luo, X., Zhang, Z., Meng, F. & Yang, J.

Journal of Cleaner Production 273, 123006 (2020). 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. 使用与NCM 622电池回收过程相关的数据集时，必须将此回收循环包含在电池电动汽车生命周期评估（LCA）中，其中功能单元被定义为1 kWh的NCM 622电池包。用户应注意数据来源于实地调研，并且应仔细考虑有关回收材料的纯度和回收过程的效率的假设。同样重要的是要考虑在适用的情况下排除原生材料生产影响。 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 huzhikang, hzk2503593129@163.com 胡志康, hzk2503593129@163.com hzk2503593129@163.com hzk2503593129@163.com 2024-04-11T16:18:56+08:00 2024-04-20T14:28:56.696980+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=a498166f-43f0-4983-afeb-bd90536de6be&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 EoL NCM battery Input 3.6 3.6 Measured Waste NCM battery 废三元电池 Sulfuric acid(98%) Input 9.6 9.6 Measured H2SO4 (98%) 硫酸 (98%) Hydrochloric acid (30%) Input 0.3 0.3 Measured HCl (30%) 盐酸 (30%) sodium hydroxide Input 16.3 16.3 Measured NaOH (30%) 氢氧化钠 (30%) Sodium carbonate Input 0.2 0.2 Measured Na2CO3 碳酸钠 Ammonia (28%) Input 1.0 1.0 Measured Ammonia (28%) 氨 (28%) 2-ethylhexyl hydrogen -2-ethylhexylphosphonate Input 0.0174 0.0174 Measured Extracting reagent P507 提取试剂P507 Kerosene Input 0.0425 0.0425 Measured Kerosene 煤油 Hydrogen peroxide Input 3.2 3.2 Measured H2O2 双氧水 water,water Input 121.6 121.6 Measured Industrial water 工业用水 Lithium carbonate Input 1.1 1.1 Measured Li2CO3 碳酸锂 Electricity Input 73.08 73.08 Measured Electricity 电 natural gas;  44.1 MJ/kg Input 1.2 1.2 Measured natural gas 天然气 Water,Water Output 86.9 86.9 Measured Waste water 废水 Ammonia Nitrogen Output 0.0005 0.0005 Measured Ammonia nitrogen 氨氮 carbon dioxide (fossil) Output 0.6 0.6 Measured Carbon dioxide (The original article did not distinguish between bio and fossil, but according to experts, this is fossil.) 二氧化碳（原文未区分bio和fossil，根据专家判断此处为fossil） sulfur dioxide Output 0.01 0.01 Measured SO2 二氧化硫 particles (> PM10) Output 3.1 3.1 Measured Dust 灰尘 polypropylene fibres (PP) Output 0.1 0.1 Measured Polypropylene 聚丙烯 copper Output 0.7 0.7 Measured Copper 铜 aluminium Output 1.8 1.8 Measured Aluminum 铝 iron Output 0.1 0.1 Measured Steel 钢铁 Ternary cathode material Output 2.1 2.1 Measured NCM Precursor 三元材料前驱体
