These AECs serve as critical components in a wide array of electronic devices, modulating current flow, and providing temporary energy storage. This data covers the scope of AEC production for various applications, as demonstrated by the investigated manufacturer's production of approximately 1.183 billion AECs in 2020. 阴极蚀刻箔生产过程生产的 0.05 毫米蚀刻铝箔主要用于制造铝电解电容器（AEC），特别是额定420V 680uf的产品。这些 AEC 是广泛电子设备不可缺少的组成部分, 用于调节电流和提供临时能量存储。该数据涵盖了AEC的多种应用范围生产量，依据2020年调查制造商生产的约11.83亿个AEC。 MEqpbSngYoK3fvx38PMc1UOQnSd.png Unit process, single operation None 无 None 无 None 无 The inventory data of capacitor production come from the AECs’ production factory in Jiangsu Province, China. The cut-off criteria of LCI data collection for each process is coverage of at least 95% of the mass and energy of the input and output flows. The inventory data of anode foil production and cathode foil production is obtained based on the analysis of the manufacturing processes and corresponding process parameters. The upstream data (i.e., aluminum ingots, separator paper, transport, electricity, and water) are acquired from the Gabi software (Version: 10.6.1.35). In detail, the profile of Chineses electricity grid from the China Electric Power Yearbook adopts the reference year 2016. The reference year of aluminum ingot production is 2015. The inaccessible data about ammonium citrate, ammonium pentaborate, NH4H2PO4, and HBO3 are estimated based on chemical equations using the existing materials (reactants) in the Gabi software. The use and end-of-life stage inventory data are obtained based on analysis and calculation. 电容器生产的库存数据来自 AEC 位于中国江苏省的生产工厂。每道工序的 LCI 数据收集的截止标准是至少覆盖输入流和输出流 95% 的质量和能量。阳极箔生产和阴极箔生产的库存数据是根据生产工艺和相应工艺参数分析获得的。上游数据（即铝锭、分选纸、运输、电力和水）来自 Gabi 软件（版本：10.6.1.35）。具体而言，《中国电力年鉴》中的中国电网概况以 2016 年为基准年。铝锭生产的基准年为 2015 年。无法获取的柠檬酸铵、五硼酸铵、NH4H2PO4 和 HBO3 数据是根据 Gabi 软件中现有材料（反应物）的化学方程式估算的。使用和报废阶段的库存数据是通过分析和计算获得的。 None 无 None 无 Zhang, C., Jing, J., Yun, L., Zheng, Y. & Huang, H.

A cradle-to-grave life cycle assessment of high-voltage aluminum electrolytic capacitors in China. J. Clean. Prod. 370, (2022). Life Cycle Inventory (LCI) data users should ensure that their assessments capture at least 95% of the mass and energy flows when utilizing this data set on AEC production. It is critical to incorporate the upstream data provided (aluminum ingots, separator paper, transport, electricity, and water) for comprehensive environmental impact analysis. The inventory data sourced from the Gabi software should reflect the corresponding regional electricity profile and aluminum ingot production's reference years (2016 for electricity, 2015 for aluminum). Data gaps for materials such as ammonium citrate, ammonium pentaborate, NH4H2PO4, and HBO3 should be addressed through estimations based upon chemical equations using reactants available in the software. Users must include use and end-of-life stage calculations in their assessments to ensure a complete life cycle evaluation. 生命周期库存（LCI）数据使用者在使用AEC生产数据集时，应确保其评估至少包括了95%的物质和能源流。在进行全面的环境影响分析时，至关重要的是要纳入提供的上游数据（铝锭、隔离纸、运输、电力和水）。源自Gabi软件的库存数据应该反映相应的区域电力概况和铝锭生产的参考年份（电力为2016年，铝为2015年）。对于氨基柠檬酸，硼酸铵，磷酸氢二铵和硼酸等材料的数据缺口，应基于软件中可用的反应物使用化学方程进行估算来解决。用户必须在评估中包含使用和产品生命周期终端阶段的计算，以确保一个完整的生命周期评价。 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 Huimin Chang, huiminchang@tsinghua.edu.cn 常慧敏, huiminchang@tsinghua.edu.cn huiminchang@tsinghua.edu.cn huiminchang@tsinghua.edu.cn 2024-01-10T09:15:50+08:00 2024-04-20T15:31:50.360232+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=13a6140a-c0e6-4d8f-b9f5-0312de53fa31&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 1037.2140000000002 1037.2140000000002 Measured Electricity [kWh] ; Production of cathode etched foil 0.05mm Al blank coil Input 518.0 518.0 Measured 0.05mm Al blank coil[kg] ; Preparation of sulfuric acid (cathode) water, deionised Input 14337.501 14337.501 Measured Deionized water [kg] ; Preparation of sulfuric acid (cathode) tap water Input 1099.385 1099.385 Measured Tap water [kg] ; Waste gas treatment sulfuric acid Input 1129.713 1129.713 Measured Sulfur acid（98%）[kg] ; Corrosion reaction  (cathode) nitric acid, without water, in 50% solution state Input 56.865 56.865 Measured Nitric acid（98%）[kg] ; Corrosion reaction  (cathode) hydrochloric acid, without water, in 30% solution state Input 189.549 189.549 Measured Hydrochloric acid（31%）[kg] ; Corrosion reaction  (cathode) sodium hydroxide, without water, in 50% solution state Input 189.549 189.549 Measured NaOH solution (30%) [kg] ; Corrosion reaction (cathode) Al coil of 0.05mm etched foil Output 369.431 369.431 Measured Al coil of 0.05mm etched foil [kg] ; Production of cathode etched foil wastewater, average Output 18687.275 18687.275 Measured Wastewater [kg] ; Production of cathode etched foil hydrogen chloride Output 0.931 0.931 Measured HCl gas [kg] ; Production of cathode etched foil Sulfuric acid Output 0.101 0.101 Measured H2SO4 gas [kg] ; Production of cathode etched foil Nitrogen oxides Output 0.115 0.115 Measured NOx   [kg] ; Production of cathode etched foil ammonia Output 0.105 0.105 Measured NH3 gas [kg] ; Sewage treatment Chemical Oxygen Demand (COD) Output 2.273 2.273 Measured COD [kg] ; Production of cathode etched foil Suspended solids, unspecified Output 1.488 1.488 Measured SS  [kg] ; Production of cathode etched foil ammonia Output 0.048 0.048 Measured NH3-N [kg] ; Production of cathode etched foil Nitrogen Output 0.19 0.19 Measured TN  [kg] ; Production of cathode etched foil
