Use advice for data set | Life Cycle Inventory (LCI) data users should ensure that their assessments capture at least 95% of the mass and energy flows when utilizing this data set on AEC production. It is critical to incorporate the upstream data provided (aluminum ingots, separator paper, transport, electricity, and water) for comprehensive environmental impact analysis. The inventory data sourced from the Gabi software should reflect the corresponding regional electricity profile and aluminum ingot production's reference years (2016 for electricity, 2015 for aluminum). Data gaps for materials such as ammonium citrate, ammonium pentaborate, NH4H2PO4, and HBO3 should be addressed through estimations based upon chemical equations using reactants available in the software. Users must include use and end-of-life stage calculations in their assessments to ensure a complete life cycle evaluation. |
Technical purpose of product or process | The cathodically etched foil production process generates 0.05 mm etched aluminum foil that is primarily used in the manufacturing of aluminum electrolytic capacitors (AECs), specifically rated at 420V and 680uf. These AECs serve as critical components in a wide array of electronic devices, modulating current flow, and providing temporary energy storage. This data covers the scope of AEC production for various applications, as demonstrated by the investigated manufacturer's production of approximately 1.183 billion AECs in 2020. |

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. | ||||
