Dismantled LiB cells will be soaked in NaOH solution to separate copper foil from cathodes and anodes. After that, the LiB cells will be put into HAc solution to separate cathodes and anodes. The cathodes will be soaked in acetone solution, then the mixture of cathodes and acetone solution will be filtered and dried, and battery materials will be recycled in this process. 废旧锂电池回收运营商首先为锂电池（2.75V以下）放电，并将电池组拆成电池。将拆下的LiB电池浸泡在NaOH溶液中，将铜箔与阴极和阳极分离。之后，将LiB电池放入HAc溶液中，以分离阴极和阳极。阴极将浸泡在丙酮溶液中，然后阴极和丙酮溶液的混合物将被过滤和干燥，电池材料将在这个过程中回收。In this research, we presume the average weight of EVs’ LiBs is 300 kg.0This hydrometallurgical recycling process is intended for the recovery of materials from spent NCM111 lithium-ion batteries (LiBs) specifically designed for electric vehicle (EV) applications. The recycled materials, such as lithium, nickel, cobalt, and manganese, are typically used to manufacture new battery cells or for other applications that require high purity chemicals.该湿法回收工艺旨在从废旧NCM111锂离子电池（应用于电动汽车）中回收材料。回收的材料，例如锂、镍、钴和锰，通常用于制造新电池单元或其他需要高纯度化学品的应用。HkoibjV8WoEIpbxZSPYclqVYnGb.pngUnit process, single operationNone无None无None无None无None无Wang, S. & Yu, J.

WASTE MANAGEMENT & RESEARCH 39, 156–164 (2021).When utilizing data from this wet recycling process of waste NCM111 cells, ensure that the focus is on the intended application of EV battery recycling. Data users should consider the average weight of EV LiBs as indicated (300 kg) for assessments and extrapolations. Attention should be paid to the chemical purity and the completeness of separation during the recycling phases. Exclusion or inclusion of upstream impacts, such as emissions associated with chemical reagent production used in the process, should be carefully considered in the analysis.在使用废旧NCM111电池湿法回收过程数据时，需确保重点关注电动汽车电池回收的预期应用。数据使用者在评估和推断时应考虑电动汽车锂电池的平均重量（300公斤）。在整个回收阶段，应注意化学纯度和分离的完整性。在分析中应仔细考虑是否排除或包含上游影响，例如与过程中使用的化学试剂生产相关的排放。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maqingyuan, m1120498928@163.com马清源, m1120498928@163.comm1120498928@163.comm1120498928@163.com2023-12-18T17:36:15+08:002024-04-20T14:28:22.965116+08:0000.01.005https://lcadata.tiangong.world/showProcess.xhtml?uuid=1807ca9a-e9ae-4385-9754-27e209615764&version=01.00.000&stock=TianGongTiangong LCI Data Working Group天工LCI数据工作小组falseFree of charge for all users and usesCathode MaterialInput218.0218.0Missing unimportantSodium Hydroxide solution（1mol/L）Input20.020.0Missing unimportantAcetic acid solution(3mol/L)Input294.0294.0Missing unimportantAcetone solution(5mol/L)Input125.0125.0Missing unimportantnickelOutput20.020.0Missing unimportantcobaltOutput20.020.0Missing unimportantlithiumOutput12.012.0Missing unimportantmanganeseOutput20.020.0Missing unimportantaluminiumOutput17.017.0Missing unimportantcopperOutput33.033.0Missing unimportantAnodes (used)Output47.047.0Missing unimportantindustrial waste (unspecified)Output471.0471.0Missing unimportantWaste (solid)Output10.510.5Missing unimportantpackaging waste (plastic)Output6.56.5Missing unimportant
