The aluminum blank foil (anode) discussed in this data set is produced for use in manufacturing aluminum electrolytic capacitors (AEC), specifically for a 420V 680uf unit process. These AECs are used mainly in electronic circuits as filters, decoupling capacitors, and for energy storage, supporting applications like power supplies, automotive electronics, and consumer electronics. 本数据集中讨论的铝空白箔（阳极）是为制造铝电解电容器（AEC）而生产的，特别是用于420V 680uf单元过程。这些AEC主要用于电子电路作为滤波器、去耦电容器以及储能，支持电源供应、汽车电子和消费电子等应用。 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.

Users of this LCA data should attribute the appropriate mass and energy flow coverage, ensuring a minimum of 95% is accounted for in the process inputs and outputs. The data set is based on the manufacturing processes for anodes and cathodes for AEC production, with upstream data from Gabi software including aluminum ingots, separator paper, transport, electricity, and water. Reference years for electricity and aluminum ingot production are 2016 and 2015, respectively. Users should note that data for certain chemicals is estimated based on similar chemical compositions available within the software. Methodological adjustments may be needed related to the use and end-of-life stage inventory data to reflect specific use phase behavior and disposal or recycling practices. 本LCA数据的用户应当正确归属所需质量和能量流的覆盖率，确保至少有95%的过程输入和输出被计入。数据集基于AEC生产的阳极和阴极的制造过程，上游数据来自Gabi软件，包括铝锭、隔离纸、运输、电力和水。电力和铝锭生产的参考年分别是2016年和2015年。用户应注意，特定化学物质的数据是基于软件内可用的相似化学组成进行估算的。可能需要对使用和生命周期结束阶段库存数据进行方法学调整，以反映特定的使用阶段行为及废弃或回收实践。 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 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 2024-04-20T15:31:50.372576+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=005cc134-fa14-497c-9eda-9e92f27ad80a&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 2273.6844 2273.6844 Measured Electricity [kWh] ; Al smelting preparation  (anode) electricity, high voltage, aluminium industry Input 111.06 111.06 Measured Electricity [kWh] ; Casting rolling (anode) electricity, high voltage, aluminium industry Input 186.8292 186.8292 Measured Electricity [kWh] ; Cold rolling 1 (anode) electricity, high voltage, aluminium industry Input 504.71999999999997 504.71999999999997 Measured Electricity [kWh] ; Intermediate annealing 1 (anode) electricity, high voltage, aluminium industry Input 1061.5212000000001 1061.5212000000001 Measured Electricity [kWh] ; Cold rolling 2 (anode) electricity, high voltage, aluminium industry Input 180.36 180.36 Measured Electricity [kWh] ; Intermediate annealing 2 (anode) electricity, high voltage, aluminium industry Input 1796.4180000000001 1796.4180000000001 Measured Electricity [kWh] ; Foil rolling  (anode) electricity, high voltage, aluminium industry Input 467.64000000000004 467.64000000000004 Measured Electricity [kWh] ; Final annealing (anode) aluminium, primary, ingot Input 1052.63 1052.63 Measured Al ingots (99.99%) [kg] ; Al smelting preparation  (anode) argon, liquid Input 0.189 0.189 Measured Ar gas [kg] ; Al smelting preparation  (anode) Graphitic lubricant Input 0.032 0.032 Measured Graphitic lubricant [kg] ; Casting rolling (anode) water, deionised Input 2.56 2.56 Measured Deionized water [kg] ; Casting rolling (anode) tap water Input 1368.421 1368.421 Measured Tap water [kg] ; Casting rolling (anode) water, deionised Input 12.093 12.093 Measured Deionized water [kg] ; Cold rolling 1 (anode) heavy fuel oil Input 0.387 0.387 Measured Rolling oil  [kg} ; Cold rolling 1 (anode) water, deionised Input 226.7475 226.7475 Measured Deionized water [kg] ; Cold rolling 2 (anode) heavy fuel oil Input 7.256 7.256 Measured Rolling oil  [kg} ; Cold rolling 2 (anode) water, deionised Input 302.33 302.33 Measured Deionized water [kg] ; Foil rolling  (anode) heavy fuel oil Input 9.675 9.675 Measured Rolling oil  [kg} ; Foil rolling  (anode) sodium hydroxide, without water, in 50% solution state Input 31.8 31.8 Measured NaOH solution (30%) [kg] ; Final annealing (anode) nitrogen, liquid Input 1.29 1.29 Measured N2 gas[kg] ; Final annealing (anode) 0.12mm Al blank coil Output 1000.0 1000.0 Measured 0.12mm Al blank coil [kg] ; Production of Al blank foil  (anode) aluminium scrap, new Output 52.24 52.24 Measured Al scraps [kg] ; Al smelting preparation  (anode) Dust Output 0.389 0.389 Measured Dust[kg] ; Al smelting preparation  (anode) wastewater, average Output 1197.5405 1197.5405 Measured Wastewater [kg] ; Production of Al blank foil  (anode) Chemical Oxygen Demand (COD) Output 0.084 0.084 Measured COD [kg] ; Production of Al blank foil  (anode) Suspended solids, unspecified Output 0.084 0.084 Measured SS [kg] ; Production of Al blank foil  (anode) BOD5, Biological Oxygen Demand Output 0.527 0.527 Measured BOD [kg] ; Production of Al blank foil  (anode) ammonia Output 0.024 0.024 Measured NH3-N [kg] ; Production of Al blank foil  (anode)
