| 数据集使用建议 | 数据使用者应关注库存数据的粒度和适用性，这些数据反映了不同类型铝电解电容器（AEC）制造过程中的特定子阶段。此数据集包含了关于LAEC以及其他两种AEC变体（PAEC和PHAEC）的信息，这些变体在介电层修复过程和导电高分子的加入方面可能存在差异。用户在将数据应用于各自的生命周期评估时，必须考虑到这些差异。基线数据的参考年份为2016年，来源于Gabi数据库；数据使用者应注意，由于制造流程的发展或自那时起环境影响的变化，可能会出现潜在的差异。方法论细节，包括从实验室数据的比例放大和对PHAEC的调整，也应在解释和使用这些数据进行环境影响评估时考虑在内，以确保准确反映当前的技术实践。 |
| 产品或过程的技术目的 | 液态铝电解电容器（LAEC）是存储电荷和能量的电子元件。这里描述的专业制造过程生产的LAEC通常大于2厘米，采用原生铝锭。生产的LAEC广泛应用于各种电子系统，如电源、消费电子及工业机械，这些场合通常需要高电容和电压额定值。由于采用了高纯度铝和不同的阳极和阴极箔片制造工艺，这些电容器也用于需要提高循环稳定性的长寿命应用。 |

| 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. |
