The foil has a thickness of 0.12 mm, making it suitable for high-voltage applications such as 420V 680uf capacitors. The data set represents industrial-scale production capabilities, signifying its significance in large-scale electronic manufacturing. 通过该工业过程生产的阳极氧化铝箔专门用于制造铝电解电容器（AECs）。这些电容器通常用于各种电子设备中，以储存电荷，供电暂时中断时使用，并过滤不需要的频率信号。箔材厚度为0.12毫米，适用于高压应用，例如420V 680uf电容器。数据集代表了工业规模的生产能力，标志着它在大规模电子制造中的重要性。 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 data set, it is crucial to adhere to the established system boundaries and cut-off criteria. Specifically, the LCI data coverage should account for at least 95% of the mass and energy inputs and outputs. Users should note that the inventory data for capacitor production is region-specific, sourced from a factory in Jiangsu Province, China. In modeling use-phase behavior and end-of-life scenarios for the capacitors, the inaccessible data for certain chemicals are estimated from chemical equations within the Gabi software using existing materials. The reference year for the energy profile of the Chinese electricity grid is 2016, and for aluminum ingot production, it is 2015. Any updates to the grid mix or technological improvements in aluminum production should be considered to ensure the data's relevancy. 使用此LCA数据集时，必须遵守既定的系统边界和截止标准。具体而言，生命周期清单（LCI）数据覆盖率应至少占输入和输出总质量和能量的95%。用户应注意，电容器生产的库存数据特定于中国江苏省的一个工厂。在模拟电容器的使用阶段行为和生命周期尾期场景时，对于某些化学品的不可获取数据是在Gabi软件内使用现有材料根据化学方程估算的。中国电网能源概况的参考年份为2016年，铝锭生产的参考年份为2015年。任何电网组合或铝生产技术改进的更新都应考虑以确保数据的相关性。 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 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 2024-04-20T15:31:50.345153+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=8a66a5d5-090f-440c-a28e-6ff29eb64f9e&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 432.16560000000004 432.16560000000004 Measured Electricity [kWh] ; Production of anode etched foil electricity, high voltage, aluminium industry Input 290.9772 290.9772 Measured Electricity [kWh] ; Hydration electricity, high voltage, aluminium industry Input 204985.2996 204985.2996 Measured 0.12mm Al blank coil Input 518.0 518.0 Measured 0.12mm Al blank coil [kg] ; Preparation of sulfuric acid (anode) water, deionised Input 107187.002 107187.002 Measured tap water Input 63287.322 63287.322 Measured Tap water [kg] ; Waste gas treatment (anode) sulfuric acid Input 470.708 470.708 Measured Sulfur acid（98%）[kg] ; Corrosion reaction (anode) nitric acid, without water, in 50% solution state Input 23.693 23.693 Measured Nitric acid（98%）[kg] ; Corrosion reaction (anode) hydrochloric acid, without water, in 30% solution state Input 78.978 78.978 Measured Hydrochloric acid（31%）[kg] ; Corrosion reaction (anode) sodium hydroxide, without water, in 50% solution state Input 78.978 78.978 Measured NaOH solution (30%) [kg] ; Corrosion reaction (anode) water, deionised Input 967.606 967.606 Measured Deionized water [kg] ; Hydration boric acid, anhydrous, powder Input 21.98 21.98 Measured HBO3 [kg] ; Formation process Ammonium Citrate Input 42.333 42.333 Measured Ammonium citrate [kg] ; Formation process Ammonium Pentaborate Input 11.611 11.611 Measured Ammonium pentaborate [kg] ; Formation process phosphoric acid, industrial grade, without water, in 85% solution state Input 120.951 120.951 Measured H3PO4 [kg] ; Passivation Ammonium dihydrogen phosphate Input 1.935 1.935 Measured NH4H2PO4 [kg] ; Phosphating Al coil of 0.12mm anode formed foil Output 449.811 449.811 Measured Al coil of 0.12 mm anode formed foil [kg] ; Production of anode formed foil Aluminium Phosphate Output 15.578 15.578 Measured AlPO4 [kg] ; Production of anode formed foil aluminium scrap, post-consumer Output 12.865 12.865 Measured Waste Al foil [kg] ; Production of anode formed foil wastewater, average Output 80795.118 80795.118 Measured Wastewater [kg] ; Production of anode formed foil Chemical Oxygen Demand (COD) Output 2.141 2.141 Measured COD [kg] ; Production of anode formed foil ammonia Output 0.372 0.372 Measured NH3-N [kg] ; Production of anode formed foil Phosphorus Output 0.036 0.036 Measured TP  [kg] ; Production of anode formed foil sewage sludge Output 14.661 14.661 Measured Sludge [kg] ; Sewage treatment wastewater, average Output 7786.269 7786.269 Measured Wastewater [kg] ; Production of anode etched foil hydrogen chloride Output 0.388 0.388 Measured HCl gas [kg] ; Production of anode etched foil Sulfuric acid Output 0.042 0.042 Measured H2SO4 gas [kg] ; Production of anode etched foil Nitrogen oxides Output 0.048 0.048 Measured NOx   [kg] ; Production of anode etched foil ammonia Output 0.044 0.044 Measured NH3 gas [kg] ; Sewage treatment Chemical Oxygen Demand (COD) Output 0.947 0.947 Measured COD [kg] ; Production of anode etched foil Suspended solids, unspecified Output 0.62 0.62 Measured SS  [kg] ; Production of anode etched foil ammonia Output 0.02 0.02 Measured NH3-N [kg] ; Production of anode etched foil Nitrogen Output 0.079 0.079 Measured TN  [kg] ; Production of anode etched foil
