Abstract
It is an object to provide an aluminum alloy foil for an electrode current collector, the foil having a high post-drying strength after application of an active material while keeping a high electrical conductivity. Disclosed is an aluminum alloy foil for an electrode current collector, comprising 0.03 to 0.1 mass % (hereinafter, 'mass %' is simply referred to as '%') of Fe, 0.01 to 0.1% of Si, and 0.0001 to 0.01% of Cu, with the rest consisting of Al and unavoidable impurities, wherein the aluminum alloy foil after final cold rolling has a tensile strength of 180 MPa or higher, a 0.2% yield strength of 160 MPa or higher, and an electrical conductivity of 60% IACS or higher; and the aluminum alloy foil has a tensile strength of 170 MPa or higher and a 0.2% yield strength of 150 MPa or higher even after the aluminum alloy foil is subjected to heat treatment at any of 120° C. for 24 hours, 140° C. for 3 hours, and 160° C. for 15 minutes.
