Aluminum electrolytic capacitor production ; Aluminum electrolytic capacitor (25V 1000uf)
数据集使用建议 Users of the LCA data set for aluminum electrolytic capacitor production should exercise caution when interpreting the environmental impacts due to the omission of specialized treating processes of production waste in the life cycle inventory (LCI). The underestimation of environmental impacts of certain chemicals attributed to estimated LCI data and unaccounted side reactions should be acknowledged. When using this LCA data, assessors should consider these limitations and possibly adjust the evaluation accordingly, especially if these conditions differ from those prevalent in the setting being assessed. Furthermore, due to simplified assumptions in the composition of the electrolyte, the data users should take note that the environmental effects could be underestimated and that they should seek more detailed data where available for higher accuracy.
产品或过程的技术目的 Aluminum electrolytic capacitors, specifically rated at 25V 1000uf, as described in the data set, are commonly integrated into electronic devices that require stable and long-lasting energy storage solutions. Their applications include power supply smoothing, filtering, or energy storage in consumer electronics, such as audio equipment, computers, and telecommunications devices, as well as in industrial and automotive electronics where higher voltage and larger capacitance are often necessary.

数据选择和组合原则 The foreground data are from an AECs’ manufacturer and its supplier. The data about the product family and manufacturing processes of capacitor fabrication are from the AECs’ manufacturer in Nantong, Jiangsu, China. The reference year of capacitor fabrication is 2021. Furthermore, through the investigation of the manufacturer’s upstream supplier, the original data of manufacturing processes of blank foil fabrication (anode and cathode), formed foil fabrication, and cathode etched foil fabrication are obtained. The reference year of blank foil fabrication, formed foil fabrication, and cathode etched foil fabrication is 2020. The background data of the substance flows (i.e., aluminum ingots, separator paper, electricity, water) from the primary industries are acquired from the Gabi software (version 10.0.0.71). The LCI data about specialized treating processes of production waste, including capacitors (waste), aluminum scraps, paper scraps, and sludge, are ignored. In the electrolyte, the complete composition of the electrolyte is 69% main solvent (1,4-butyrolactone), 26% auxiliary solvent (ammonium tetramethyl succinate), and 5% solute (water). The electrolyte here is assumed to consist of 95% of the main solvent and 5% solutes to simplify the analysis of environmental impacts due to the missing LCI data. The inaccessible LCI data about 1,4-butyrolactone, ammonium citrate, ammonium pentaborate, NH4H2PO4, and HBO3 are estimated according to chemical equations of the existing substance flows (reactants) in Gabi software. This will underestimate the environmental impact of these substances in actual industrial production to a certain extent. Besides, many chemical reactions need to satisfy various reaction conditions such as pressure, temperature, and catalyst, which will lead to the extra input of energy and raw materials and increase the risk of environmental pollution. If there are side reactions for the desired chemical reaction, it will not only affect the yield of the targeted product of the reaction but also need a suitable subsequent treatment process to separate and purify the product. Due to the limited consumption of these five materials, their influence on the final assessment result is not significant.
