| 数据集使用建议 | 该数据集所提供的清单数据来自三种类型铝电解电容器（包括LAECs、PAECs和PHAECs）的生产过程的不同阶段。用户应考虑特定的制造差异，特别是Al2O3介电质膜的修复条件和导电聚合物的引入。数据集基于2016年从Gabi数据库中获取的数据以及调查制造商提供的信息。为了进行最准确的影响评估，用户应遵循支持文档中提供的详细生命周期清单（LCI）数据和方法学（支持信息B，第5-7页为清单数据，第2页为单位影响），确保在LCA上下文中的适当应用。如果评估中使用了不同的年份或生产技术，则应考虑调整以反映技术进步和能耗变化。 |
| 产品或过程的技术目的 | 该数据集提供了聚合物铝电解电容器（PAECs）生产过程的概述，这些电容器主要用于电子设备的能量存储和过滤应用。这些电容器，特别是尺寸大于2厘米的，使用高纯度铝锭和各种过程（如熔化、铸造、轧制、退火、蚀刻和涂层）来生产阳极和阴极箔。适用于在老化过程中无需使用电解液即可修复介电质，并在箔间引入PEDOT等导电聚合物的应用场景。 |

| 关于数据集的一般性意见 | The manufacturing stage of the AECs is divided into several sub-stages in this study based on the actual fabrication segmentation in the AEC industry. First, the high-purity aluminum ingots will be smelt, cast, rolled, and annealed into the aluminum foil with a thickness of about 10–100 μm. Then, anode foil and cathode foil for the AECs will be fabricated, respectively. The same manufacturing processes are applied toward anode foil in three types of AECs. The aluminum blank foil will be etched by the weak acids to increase the superficial area of the foil, and the electrochemical reaction can further form the dielectric (Al2O3). But cathode foil of three types of AECs varies in structure and manufacturing processes due to the differences in electrolytes. The cathode foil of LAECs is made by the etched process, while the cathode foil of PAEC is made by the carbon coating process after the etched process. In PHAECs, when liquid-state electrolyte and solid-state polymer are used simultaneously, the carbon-coated cathode aluminum foil of the PAECs is also replaced by the aluminum foil with TiO2 film to overcome the potential problems on capacitor cycling life. After obtaining the anode and cathode foil, the AECs can be manufactured, assembled, and packed. Besides, there are some differences in the AEC fabrication sub-stage. The specific processes of the three types of AECs are shown in Fig. 2. In detail, the differences in manufacturing processes among the three types of AECs are mainly due to the change of repair conditions of the capacitor dielectric (Al2O3 film) and the introduction of conductive polymer. On the one hand, PAECs and PHAECs cannot use the electrolyte to repair the dielectric layer in the aging process like LAECs, so an additional forming solution is required to perform forming process, which adds extra manufacturing steps. On the other hand, the conductive polymer needs to be effectively introduced into the middle of anode and cathode foils. The conductive polymer (PEDOT) in PAECs is formed by the polymerization reaction of EDOT and oxidizing agents in the capacitor manufacturing process, while the conductive polymer (PEDOT:PSS) in PHAEC is introduced into the capacitors by the dispersive solution. The collected inventory data of LAECs, PAECs, and PHAECs by the FU are summarized in Table 2. The details of the inventory data are available in Sheets 5–7 of Supporting Info B. |
