Abstract
A method for producing high quality electrolytic aluminum foil excellent in peelability from a cathode surface is provided. A method for producing electrolytic aluminum foil according to the present disclosure is a method for producing electrolytic aluminum foil, comprising steps of depositing an aluminum film on a surface of a cathode in an electrolytic cell supplied with an electrolytic solution and comprising the cathode; and peeling the deposited aluminum film from the surface of the cathode to provide aluminum foil, wherein the cathode has surface roughness of an arithmetic average roughness (Ra) of 0.10 to 0.40 μm and a ten-point average roughness (Rz) of 0.20 to 0.70 μm.
Claims6
A method for producing electrolytic aluminum foil, comprising:
