Aluminum electrolytic capacitor production ; Aluminum blank foil production (Anode) ; Aluminum formed foil coil (Anode, 0.12mm) ; Aluminum ingot (99.99%)
Use advice for data set 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.
Technical purpose of product or process 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.

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.
