Name
Aluminum electrolytic capacitor production ; Cathode foil slitting ; Cathode etched foil coil (0.05 mm)
Use advice for data set When using the provided Life Cycle Inventory (LCI) data relevant to aluminum electrolytic capacitor production, it is essential to observe the specified cut-off criteria, ensuring coverage of at least 95% of the mass and energy of the input and output flows. Data users should be aware that the reference years for the electricity grid and aluminum ingot production are 2016 and 2015, respectively. For elements like ammonium citrate, ammonium pentaborate, NH4H2PO4, and HBO3, where data is inaccessible, users should apply estimations based on chemical equations using reactants available within the Gabi software. Data on use and end-of-life stages are derived from analysis and calculation and should be applied accordingly during LCA studies.
Technical purpose of product or process The described industrial process involves the production of aluminum electrolytic capacitors, specifically the creation of the cathodes used in aluminum electrolysis. The process includes slitting cathode foil and manufacturing aluminum coils with 0.05 mm cathode-etched aluminum foil. These components are crucial for fabricating 420V 680uf capacitor units, which are utilized in various electronics for energy storage and filtering. The capacitors produced are suitable for a wide range of applications that require durable and reliable electronic components.

Data selection and combination principles 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.
