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. 使用此生命周期评估数据时，用户应确保方法学边界与其具体应用相对应。注意以1 kWh能量内容比较作为参考基准。该数据源自多篇论文，因此实务者必须确保数据与其上下文的一致性和相关性。可能需要排除与所讨论的特定回收流程不适用的步骤，例如不同电池化学成分的过程，并且用户应在其评估中考虑技术变异和区域实践。 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 2024-04-11T16:00:26+08:00 2024-04-20T14:28:28.685396+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=765d5fae-ccea-45d1-936d-6802668c46cf&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 Sulphuric acid Input 9.54 9.54 sodium hydroxide Input 5.79 5.79 Hydrogen peroxide (30%) Input 3.25 3.25 Hydrogen peroxide production mix/DE 过氧化氢生产混合物/DE Lithium carbonate Input 0.39 0.39 Lithium carbonate, production mix/CN 碳酸锂，生产混合物/CN Electricity Input 11.83 11.83 natural gas,natural gas Input 6.81 6.81 Carbon dioxide (fossil) Output 0.18 0.18 The original text does not distinguish between bio and fossil, and according to experts, it is fossil here 原文未区分bio和fossil，根据专家判断此处为fossil copper Output 0.04 0.04 Ni-rich NMC Output 2.63 2.63 aluminium Output 0.14 0.14
