Abstract
An object of the present invention is to provide an aluminum alloy foil for an electrode current collector, the foil having a high strength and high strength after a drying process. The aluminum alloy foil can be manufactured at low cost. Disclosed is an aluminum alloy foil for electrode current collector, including 0.03 to 1.0% of Fe, 0.01 to 0.2% of Si, 0.0001 to 0.2% of Cu, 0.005 to 0.03% of Ti, with the rest being Al and unavoidable impurities. The aluminum alloy foil has Fe solid solution content of 200 ppm or higher, and an intermetallic compound having a maximum diameter length of 0.1 to 1.0 μm in an number density of 2.0×10particles/mmor more.
