Use advice for data set | When using this LCA data set, it is crucial to adhere to the established system boundaries and cut-off criteria. Specifically, the LCI data coverage should account for at least 95% of the mass and energy inputs and outputs. Users should note that the inventory data for capacitor production is region-specific, sourced from a factory in Jiangsu Province, China. In modeling use-phase behavior and end-of-life scenarios for the capacitors, the inaccessible data for certain chemicals are estimated from chemical equations within the Gabi software using existing materials. The reference year for the energy profile of the Chinese electricity grid is 2016, and for aluminum ingot production, it is 2015. Any updates to the grid mix or technological improvements in aluminum production should be considered to ensure the data's relevancy. |
Technical purpose of product or process | The anodized aluminum foil produced through this industrial process is specifically designed for use in manufacturing aluminum electrolytic capacitors (AECs). These capacitors are commonly utilized in various electronic devices to store electrical charge, supply power during momentary interruptions, and filter unwanted frequency signals. The foil has a thickness of 0.12 mm, making it suitable for high-voltage applications such as 420V 680uf capacitors. The data set represents industrial-scale production capabilities, signifying its significance in large-scale electronic manufacturing. |

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. | ||||
