Use advice for data set When using this life cycle inventory (LCI) data, ensure that the scope of your assessment aligns with the coverage of at least 95% of mass and energy flows as per the cut-off criteria. The inventory encompasses anode and cathode foil production along with the relevant upstream data sourced from Gabi software, matching the technological background of the year 2016 for the Chinese electricity grid, and 2015 for aluminum ingot production. Users should note that certain data regarding chemicals were estimated using equivalent materials available within the software, hence adjustments may be necessary when modelling for precision-critical applications. It is advised to consider the use phase behavior and end-of-life inventory data cautiously, especially in systems where the capacitor's performance might have a significant impact.
Technical purpose of product or process This data set describes the production process of 0.12mm anode formed foil aluminum rolls used as current collector foils in lithium-ion batteries, and slitting process involved in Aluminum Electrolytic Capacitor (AEC) manufacturing. These components are crucial in the electronics industry for high-performance energy storage solutions, such as those found in portable consumer electronics, electric vehicles, and stationary energy storage systems. The production data pertains to a factory in Jiangsu Province, China, reflecting large scale industrial manufacture of AECs with applications in various electronic devices requiring capacitors for circuit functionality.

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.
