Use advice for data set | This LCA data set should be applied with the understanding that the reference year of the elementary data is around 2016, and it was acquired from the Gabi database (Version: 10.6.1.35). When using this data, attention should be paid to the technological relevance of the raw materials, and the transportation data should reflect the supply chain from source to end user. For those substances not found in the Gabi database, estimations based on chemically similar reactions from existing raw materials should be applied cautiously. The LCA data, especially regarding the preparation process of dispersive solutions and cathode foil fabrication for PHAECs, should be scaled from lab data judiciously due to the adjustments made from similar processes in PAECs. |
Technical purpose of product or process | Polymer Aluminum Electrolytic Capacitors (PAEC) represented by this data set are commonly used for energy storage in a variety of electronic equipment, ranging from consumer electronics to industrial applications where high capacitance and compactness are required.

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. | ||||
