Abstract
An object of the present invention is to provide an aluminum alloy foil for an electrode current collector and a manufacturing method thereof, the foil having a high strength and high strength after a drying process after the application of the active material while keeping a high electrical conductivity. Disclosed is a method for manufacturing an aluminum alloy foil for electrode current collector, including: forming by continuous casting an aluminum alloy sheet containing 0.03 to 1.0% of Fe, 0.01 to 0.2% of Si, 0.0001 to 0.2% of Cu, with the rest being Al and unavoidable impurities, performing cold rolling to the aluminum alloy sheet at a cold rolling reduction of 80% or lower, and performing heat treatment at 550 to 620° C. for 1 to 15 hours.
