Document Type and Number:
WIPO Patent Application WO/2018/097152
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a high-quality electrolytic aluminum foil that has a smooth surface and is free of dendritic deposits on the ends thereof; and a manufacturing method allowing electrolytic aluminum foil to be obtained at a high yield. This electrolytic aluminum foil has a surface arithmetic mean height (Sa) of 0.15 μm or less, and, with regard to the size of the crystal grains present in a cross-section, satisfies the formulas (x+y)/2 ≤ 3 μm and 1 ≤ x/y ≤ 4, wherein x is a first maximum dimension (μm) as measured in the thickness direction of the cross section, and y is a second maximum dimension (μm) as measured in the width direction of the cross section.
