Use advice for data set | Please note that the LCI data for the LAECs manufacturing is specific to the year around 2016 and sourced from the Gabi database (Version 10.6.1.35); thus, temporal relevance must be considered when applying this data to current or future assessments. Users should adjust for technological developments that may have occurred post-2016. Furthermore, specific methodological advice includes taking into account the confidentiality limitations surrounding the manufacturing LCI data of the aluminum cathode foil for PHAECs. Attention should also be directed towards appropriate scaling of lab data for dispersive solution preparation (PEDOT:PSS, 1%wt). For the transportation stage, the supply chain data should reflect the journey of raw materials to the manufacturer and the manufactured capacitors to the end customers. Appropriate end-of-life treatment data must also be leveraged to ensure a comprehensive analysis. Users should also seek to use supplementary background data for materials like EDOT, ammonium adipate, and ammonium citrate, which are not present in the Gabi database. |
Technical purpose of product or process | Liquid Aluminum Electrolytic Capacitors (LAECs) are primarily used in electronic devices for energy storage and filtering purposes. They are employed in various applications, including power supply units, audio equipment, and inverter systems, where their high capacitance and voltage ratings are essential. The data set represents the life cycle inventory (LCI) of LAECs, which is used to assess their environmental impact across their lifecycle, from raw material extraction through to manufacturing, use, and end-of-life disposal or recycling. |

Data selection and combination principles | The material information and performance parameters of the three types of AECs are from the investigated manufacturer. Moreover, through the field research of several factories in the AEC industry, the original data on aluminum blank foil fabrication (made from aluminum ingots), anode/cathode foil fabrication (made from aluminum blank foil), and capacitor fabrication were obtained. Due to technical confidentiality, the LCI data of the fabrication of the cathode foil for PHAECs cannot be obtained directly from the supplier. Therefore, the manufacturing LCI of aluminum cathode foil in PHAECs is adjusted according to the coating process data of cathode foil of PAECs, considering their similarity. In the transportation stage, the data of the main raw materials from the material origin to the capacitor manufacturer and the data of the manufactured capacitor products from the manufacturer to the customers are from the supply chain system of the manufacturer. The energy consumption in the use stage is calculated based on the physical equations and the electrical parameters of the AECs. To ensure the completeness of the analysis, the data of the end-of-life stage is obtained based on the analysis and calculation.The reference year of the elementary data is around 2016. The elementary data (i.e., aluminum ingots, separator paper, transport, electricity, and water) are acquired from the Gabi database (Version: 10.6.1.35). In addition, some background data, including 3, 4-ethylene dioxythiophene (EDOT), ammonium adipate, ammonium citrate, etc., are not available in the Gabi database. They are estimated based on the chemical reactions with the material preparation process from the existing raw materials in the Gabi database. The data on the preparation process of the dispersive solution (PEDOT:PSS, 1%wt) for PHAECs' fabrication are scaled from the lab data. The detailed LCI data of the three types of AEC and unit impact of the substance flow is provided in Sheets 5–7 and Sheet 2 of Supporting Info B. | ||||
