Key Data Set Information
Location JS-CN
Reference year 2020
Name
Aluminum electrolytic capacitor production ; components before soaking ; winding
Use advice for data set When utilizing the inventory data in Life Cycle Assessments, ensure the inclusion of all input and output flows that account for at least 95% of the mass and energy according to the set cut-off criteria. The provided data is specific to AECs’ production within the reference years 2015 and 2016 for aluminum ingot production and Chinese electricity grid profile respectively. Adjustments may be required for studies reflecting different time frames or technological improvements. The inventory data for the upstream processes such as aluminum ingots, separator paper, and transportation, acquired from Gabi software, must be used with an understanding of the underlying assumptions and limitations. Where data was inaccessible, estimates based on chemical equations using existing materials in Gabi software were made; users must take into account these estimations' uncertainties. For use and end-of-life stage data, rely on methodological consistency with the inventory analysis and calculations provided.
Technical purpose of product or process The aluminum electrolytic capacitors (AECs) with a specification of 420V 680uf are used primarily within the electronics industry for applications such as power supply smoothing, filtering, or energy storage in various devices, where a stable and reliable capacitor is necessary for the operation. They are suited for high voltage and large capacity needs.

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.
