The aluminum blank foil (cathode) produced in this process is used in the manufacture of aluminum electrolytic capacitors (AECs), which are components typically utilized in electronic circuits for smoothing, filtering, and energy storage purposes. The capacitors produced, rated at 420V, 680uf, can be deployed in various electronic devices for single unit processes that require high voltage and capacity. 该工艺生产的铝空白箔（阴极）用于制造铝电解电容器（AEC），这些组件通常用于电子电路中的平滑、过滤和储能。所生产的电容器规格为420V、680uf，可用于需要高电压和容量的各种电子设备中的单元过程。 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). When using this LCA dataset, it is important to ensure that the conditions of the processes align with those detailed: the use of 0.05 mm aluminum billet coil and aluminum ingots in the production of AECs. The reference data for inputs like electricity should correspond to the profile of the Chinese grid for the year 2016, and aluminum ingot production should be based on the 2015 data. Exclude data not covering at least 95% of mass and energy inputs/outputs in the life cycle inventory (LCI). Estimations for inaccessible data on certain chemicals must be derived from related chemical equations via the Gabi software. For assessments of the use phase and end-of-life stages, analyses and respective calculations need to be performed to accurately reflect these stages in the life cycle of the product. 使用该生命周期评估（LCA）数据集时，重要的是确保过程条件与详细说明一致：在铝电解电容器的生产中使用0.05 mm铝坯卷材和铝锭。输入数据如电力对应的参考数据应符合2016年中国电网的概况，铝锭生产应基于2015年的数据。排除LCI数据中不覆盖至少95%的质量和能量输入/输出的数据。对于无法访问的某些化学品数据，必须通过Gabi软件从相关化学方程式导出估算。对于使用阶段和生命周期终期阶段的评估，需要进行分析和相应的计算，以准确反映产品生命周期中这些阶段。 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 2024-04-20T15:31:50.386403+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=15d328e9-1213-4b7b-b83d-be86c7d7ed40&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 2204.082 2204.082 Measured Electricity [kWh] ; Al smelting preparation  (cathode) electricity, high voltage, aluminium industry Input 111.04560000000001 111.04560000000001 Measured Electricity [kWh] ; Casting rolling (cathode) electricity, high voltage, aluminium industry Input 186.804 186.804 Measured Electricity [kWh] ; Cold rolling 1 (cathode) electricity, high voltage, aluminium industry Input 504.71999999999997 504.71999999999997 Measured Electricity [kWh] ; Intermediate annealing 1 (cathode) electricity, high voltage, aluminium industry Input 1698.2028 1698.2028 Measured Electricity [kWh] ; Cold rolling 2 (cathode) electricity, high voltage, aluminium industry Input 180.36 180.36 Measured Electricity [kWh] ; Intermediate annealing 2 (cathode) electricity, high voltage, aluminium industry Input 4310.823600000001 4310.823600000001 Measured Electricity [kWh] ; Foil rolling  (cathode) electricity, high voltage, aluminium industry Input 467.64000000000004 467.64000000000004 Measured Electricity [kWh] ; Final annealing (cathode) aluminium, primary, ingot Input 1020.41 1020.41 Measured Al ingots (99.9%) [kg] ; Al smelting preparation  (cathode) argon, liquid Input 0.184 0.184 Measured Ar gas [kg] ; Al smelting preparation  (cathode) 戳啦 Graphitic lubricant Input 0.032 0.032 Measured Graphitic lubricant [kg] ; Casting rolling (cathode) water, deionised Input 2.56 2.56 Measured Deionized water [kg] ; Casting rolling (cathode) tap water Input 1326.531 1326.531 Measured Tap water [kg] ; Casting rolling (cathode) water, deionised Input 12.092 12.092 Measured Deionized water [kg] ; Cold rolling 1 (cathode) heavy fuel oil Input 0.387 0.387 Measured Rolling oil  [kg} ; Cold rolling 1 (cathode) water, deionised Input 362.747 362.747 Measured Deionized water [kg] ; Cold rolling 2 (cathode) heavy fuel oil Input 11.608 11.608 Measured Rolling oil  [kg} ; Cold rolling 2 (cathode) water, deionised Input 725.494 725.494 Measured Deionized water [kg] ; Foil rolling  (cathode) heavy fuel oil Input 23.216 23.216 Measured Rolling oil  [kg} ; Foil rolling  (cathode) sodium hydroxide, without water, in 50% solution state Input 31.8 31.8 Measured NaOH solution (30%) [kg] ; Final annealing (cathode) nitrogen, liquid Input 1.29 1.29 Measured N2 gas[kg] ; Final annealing (cathode) flow错啦 0.05mm Al blank coil Output 1000.0 1000.0 Measured 0.05mm Al blank coil [kg] ; Production of Al blank foil  (cathode) aluminium scrap, new Output 20.03 20.03 Measured Al scraps [kg] ; Al smelting preparation  (cathode) Dust Output 0.378 0.378 Measured Dust[kg] ; Al smelting preparation  (cathode) wastewater, average Output 2620.924 2620.924 Measured Wastewater [kg] ; Production of Al blank foil  (cathode) Chemical Oxygen Demand (COD) Output 0.183 0.183 Measured COD [kg] ; Production of Al blank foil  (cathode) Suspended solids, unspecified Output 0.183 0.183 Measured SS [kg] ; Production of Al blank foil  (cathode) BOD5, Biological Oxygen Demand Output 1.153 1.153 Measured BOD [kg] ; Production of Al blank foil  (cathode) ammonia Output 0.052 0.052 Measured NH3-N [kg] ; Production of Al blank foil  (cathode)
