The data about the product family and manufacturing processes of capacitor fabrication are from the AECs’ manufacturer in Nantong, Jiangsu, China. The reference year of capacitor fabrication is 2021. Furthermore, through the investigation of the manufacturer’s upstream supplier, the original data of manufacturing processes of blank foil fabrication (anode and cathode), formed foil fabrication, and cathode etched foil fabrication are obtained. The reference year of blank foil fabrication, formed foil fabrication, and cathode etched foil fabrication is 2020. The background data of the substance flows (i.e., aluminum ingots, separator paper, electricity, water) from the primary industries are acquired from the Gabi software (version 10.0.0.71). The LCI data about specialized treating processes of production waste, including capacitors (waste), aluminum scraps, paper scraps, and sludge, are ignored. In the electrolyte, the complete composition of the electrolyte is 69% main solvent (1,4-butyrolactone), 26% auxiliary solvent (ammonium tetramethyl succinate), and 5% solute (water). The electrolyte here is assumed to consist of 95% of the main solvent and 5% solutes to simplify the analysis of environmental impacts due to the missing LCI data. The inaccessible LCI data about 1,4-butyrolactone, ammonium citrate, ammonium pentaborate, NH4H2PO4, and HBO3 are estimated according to chemical equations of the existing substance flows (reactants) in Gabi software. This will underestimate the environmental impact of these substances in actual industrial production to a certain extent. Besides, many chemical reactions need to satisfy various reaction conditions such as pressure, temperature, and catalyst, which will lead to the extra input of energy and raw materials and increase the risk of environmental pollution. If there are side reactions for the desired chemical reaction, it will not only affect the yield of the targeted product of the reaction but also need a suitable subsequent treatment process to separate and purify the product. Due to the limited consumption of these five materials, their influence on the final assessment result is not significant. 三种 AEC 的材料信息和性能参数均来自被调查的制造商。此外，通过对 AEC 行业的几家工厂进行实地调研，获得了铝坯箔制造（由铝锭制成）、阳极/阴极箔制造（由铝坯箔制成）和电容器制造的原始数据。由于技术保密原因，无法直接从供应商处获得 PHAEC 阴极箔制造的 LCI 数据。因此，考虑到两者的相似性，根据 PAECs 阴极箔的涂层工艺数据调整 PHAECs 阴极铝箔的制造 LCI。在运输阶段，主要原材料从材料产地到电容器制造商的数据以及电容器制成品从制造商到客户的数据均来自制造商的供应链系统。使用阶段的能耗是根据 AEC 的物理方程和电气参数计算得出的。为确保分析的完整性，在分析和计算的基础上获得报废阶段的数据。基本数据的参考年份约为 2016 年。基本数据（即铝锭、分离纸、运输、电力和水）来自 Gabi 数据库（版本：10.6.1.35）。此外，一些背景数据，包括 3，4-乙烯二氧噻吩（EDOT）、己二酸铵、柠檬酸铵等，在 Gabi 数据库中无法获得。它们是根据 Gabi 数据库中现有原材料在材料制备过程中发生的化学反应估算出来的。用于制造 PHAECs 的分散溶液（PEDOT:PSS，1%wt）的制备过程数据是根据实验室数据按比例计算的。三种 AEC 的详细 LCI 数据和物质流的单位影响见辅助信息 B 的第 5-7 张和第 2 张。 None 无 None 无 Zhang, C., Zheng, Y., Huang, H., Liu, Z. & Jing, J.

(2022) Zhang, C., Zheng, Y., Huang, H., Liu, Z. & Jing, J. Environmental impact assessment of aluminum electrolytic capacitors in a product family from the manufacturer’s perspective. Int. J. Life Cycle Assess. (2022) When utilizing this data set, users should pay attention to the following methodological guidelines: consider the inclusion of production waste treatment not covered by the provided data, include adjustments for environmental impact underestimation due to estimated LCI data for certain chemicals, and ensure the calculation of additional energy and raw material inputs for satisfying various reaction conditions. Additionally, consider the potential environmental risk due to side reactions and subsequent treatment processes. Note that the missing LCI data may lead to a certain degree of underestimation of environmental impacts in actual industrial production, and due to the limited quantities involved, the overall effect on the LCA results is deemed not significant. 使用这个数据集时，用户应注意以下方法指导：考虑未涵盖在所提供数据内的生产废物处理的纳入、对于因某些化学品的LCI数据估算而欠低估的环境影响进行调整，确保为满足多种反应条件而计算额外的能源和原材料输入。另外，还应考虑由于副反应及后续处理过程可能带来的潜在环境风险。请注意，由于缺失的LCI数据可能会导致实际工业生产中环境影响的某种程度的低估，且由于涉及的数量有限，对整体LCA结果的影响被认为不显著。 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 Jinliang Xie, jinliang.research@gmail.com 谢金良, jinliang.research@gmail.com jinliang.research@gmail.com jinliang.research@gmail.com 2024-01-10T09:14:45+08:00 2024-04-20T15:31:36.532161+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=aa36e44a-7165-4fb1-b6eb-412b9b66c7ba&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 electricity, high voltage, aluminium industry Input 12507.300000000001 12507.300000000001 Measured Aluminum ingots(anode) Input 342.88 342.88 Measured Al ingots (anode) ; Al smelting preparation (anode) Aluminum ingots(cathode) Input 182.02 182.02 Measured Al ingots (cathode) Lead, in ground Input 25.31 25.31 Measured Lead from assembly (including sleeving) case from assembly (including sleeving) Input 612.27 612.27 Measured case from assembly (including sleeving) polysulfide, sealing compound Input 166.24 166.24 Measured Sealing cover from assembly (including sleeving) Sleeve Input 35.8 35.8 Measured sleeve from assembly (including sleeving) Armature Winding Input 25.31 25.31 Measured tab from winding ; 绕组接线片 sealing tape, aluminium/PE, 50 mm wide Input 2.7 2.7 Measured tape from winding Separator Paper Coil,Separator Paper Coil Input 102.46 102.46 Measured Separator paper coil water, deionised Input 87996.54 87996.54 Measured deionized water tap water Input 49376.39 49376.39 Measured tape water electrolyte, KOH, LiOH additive Input 312.13 312.13 Measured Electrolyte (soak); The complete composition of electrolyte is 69% main solvent (1,4-butyrolactone), 26% auxiliary solvent (ammonium tetramethylsuccinate), and 5% solute (water).
