Document Type and Number:
WIPO Patent Application WO/2022/137582
Kind Code:
A1
Abstract:
The present invention provides an electrode foil with high capacitance per unit volume. Provided is an electrode foil for an electrolytic capacitor. This electrode foil extends in a longitudinal direction and has a width direction that is orthogonal to the longitudinal direction. The electrode foil includes an expanded surface portion on a surface of the electrode foil, and cracks are formed in the expanded surface portion in a direction oblique to the width direction.
