foil is also cut into strips (2.8 9 30.3 cm) and the electrode lead bar is typically used as lead to collect the current, while the electrode lead wire is physi-cally stitched to the anode foil, that is, Al/Al 2O 3 anode electrode. The AC/Al cathode and Al/Al 2O 3 anode electrode are in turn separated by electrolytic

An electrolytic capacitor is a polarized capacitor whose anode or positive plate is made of a metal that forms an insulating oxide layer through anodization.This oxide layer acts as the dielectric of the capacitor. A solid, liquid, or gel electrolyte covers the surface of this oxide layer, serving as the cathode or negative plate of the capacitor.
tance of the aluminum cathode foil is much higher than that of the aluminum anode foil so that the applied voltage appears mainly on the aluminum anode foil, which deter-mines the operation voltage and the capacitance. Therefore, in this study, we were concerned with the aluminum anode foil. To achieve a smaller size of the aluminum electrolytic
