example 1
[0062] An aluminum electrolytic capacitor with a coiled structure was prepared according to the following steps.
[0063] First, the aluminum foil is electrochemically corroded, and then anodized to form an anodized film on the entire surface of the aluminum foil, and then connected to a wire joint that leads out the electrode to obtain an aluminum anode electrode. The other aluminum foil is also electrochemically etched, and a lead terminal of an extraction electrode is connected to the foil to form an aluminum cathode foil. Next, a capacitor element was prepared by inserting a separator between the anode electrode and the cathode electrode, followed by crimping. The release paper used here is a paper prepared by using Manila hemp as a raw material. Its cation content is as low as 489ppm due to the washing steps employed in the papermaking process. Then use the electrolytic solution described below to impregnate the capacitor element, and place it in a closed-end aluminum s...
example 2 and 3
[0070] In these two examples, except that the cation content in the release paper used was adjusted to 280ppm (example 2) or 120ppm (example 3), the same process as example 1 was repeated, and the results shown in Table 1 below were obtained. Comparative Examples 1 to 3
