Use advice for data set 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.
Technical purpose of product or process 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.

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.
