| 数据集使用建议 | 使用PHAEC生产的LCA数据时，请考虑数据集的参考年份（2016年）和来源（Gabi数据库版本10.6.1.35），以确保环境影响评估的准确性。仅将详细的生命周期清单（LCI）数据整合应用于PHAEC制造，并考虑与LAECs相比在制造过程中使用的额外成型溶液。特别注意导电聚合物（PEDOT、PEDOT:PSS）的引入，并在PHAECs的阴极箔LCI数据不可用时，使用来自PAECs的类似工艺调整制造LCI。对于终生阶段的考虑，使用提供的分析和计算来全面评估环境影响。 |
| 产品或过程的技术目的 | 聚合物杂化铝电解质电容器（PHAECs）旨在用于高性能电子应用，其中固态聚合物和液态电解质的结合为电容器组件提供了改进的使用寿命和稳定性。它们通常用于电源电路、能量储存系统和需要可靠和长寿命电容器的电子设备（电容器大于2厘米）。 |

| 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. |
