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) Users of the LCA data set for aluminum electrolytic capacitor production should exercise caution when interpreting the environmental impacts due to the omission of specialized treating processes of production waste in the life cycle inventory (LCI). The underestimation of environmental impacts of certain chemicals attributed to estimated LCI data and unaccounted side reactions should be acknowledged. When using this LCA data, assessors should consider these limitations and possibly adjust the evaluation accordingly, especially if these conditions differ from those prevalent in the setting being assessed. Furthermore, due to simplified assumptions in the composition of the electrolyte, the data users should take note that the environmental effects could be underestimated and that they should seek more detailed data where available for higher accuracy. 使用铝电解电容器生产生命周期评估（LCA）数据集的用户在解释环境影响时应谨慎，由于生命周期清单（LCI）中忽略了生产废物的专业处理过程。由于基于估计的LCI数据和未考虑的副反应，某些化学物质环境影响的低估应予以认可。在使用此LCA数据时，评估者应考虑这些限制，并可能相应调整评估，特别是如果这些条件与被评估环境中的常见条件不同。此外，由于在电解液成分的简化假设下，数据用户应注意环境效应可能被低估，并且他们应当在可行的情况下寻找更详细的数据以提高准确性。 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 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 2024-04-20T15:31:36.516331+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=81b4d178-1f79-4ea7-aef1-36b42d90d41c&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 3526.38 3526.38 Measured Aluminum ingots(anode) Input 71.9 71.9 Measured Al ingots (anode) ; Al smelting preparation (anode) Aluminum ingots(cathode) Input 41.04 41.04 Measured Al ingots (cathode) Lead, in ground Input 10.33 10.33 Measured Lead from assembly (including sleeving) Ferrite Beads, Cores and Sleeves Input 242.86 242.86 Measured case from assembly (including sleeving) Sleeve Input 14.45 14.45 Measured sleeve from assembly (including sleeving) polysulfide, sealing compound Input 64.14 64.14 Measured Sealing cover from assembly (including sleeving) Armature Winding Input 10.33 10.33 Measured tab from winding ; 绕组接线片 sealing tape, aluminium/PE, 50 mm wide Input 1.87 1.87 Measured tape from winding Separator Paper Coil,Separator Paper Coil Input 28.56 28.56 Measured Separator paper coil water, deionised Input 18533.94 18533.94 Measured deionized water tap water Input 10363.5 10363.5 Measured tape water electrolyte, KOH, LiOH additive Input 85.81 85.81 Measured Electrolyte (soak); The complete composition of electrolyte is 69% main solvent (1,4-butyrolactone), 26% auxiliary solvent (ammonium tetramethylsuccinate), and 5% solute (water).
