Abstract
The present invention provides an aluminum alloy foil, capable of going under thin rolling during its manufacture. The aluminum alloy foil shall also avoid cuts during the active material paste coating process and wrinkles during the press working process, and have suitable strength for the series of manufacturing processes from the manufacture of the aluminum alloy foil to the manufacture of the electrode material. Further, the present invention provides an aluminum alloy foil for electrode current collector, including 0.50 to 1.50 mass % (hereinafter mass % is referred to as %) of Mn, 0.05 to 0.50% of Cu, 0.20 to 1.00% of Fe, 0.01 to 0.60% of Si, with the rest consisting of Al and unavoidable impurities, a manufacturing method thereof, and an electrode material. Here, regarding the aluminum alloy foil, a solid solution amount of Mn is 1500 ppm or more, a solid solution amount of Cu is 40 ppm or more, and a tensile strength after a final cold rolling (T1) is 260 MPa or higher and 350 MPa or lower.
