Abstract: An aluminum-alloy foil that enables to satisfy both of high elongation and high strength even in the case of reducing the foil thickness. The chemical composition of the aluminum-alloy foil contains, in mass %, Fe: 1.0% or more and 2.0% or less, Cu: 0.1% or more and 0.5% or less, and Mn: 0.05% or less, the remainder being Al and unavoidable impurities. The aluminum-alloy foil has a foil thickness of 20 μm or less, and satisfies the relation El≥100×t/UTS. Here, t represents a foil thickness (μm), UTS represents a tensile strength (MPa), and El represents an elongation (%).

Abstract: A method for manufacturing porous aluminum, comprising steps of: press-molding a powder mixture of aluminum powder and supporting powder under pressure of not lower than 200 MPa, the aluminum powder having a volume ratio of 5 to 30% with respect to a total volume of the powder mixture; sintering a press-molded body with heat treatment in an inert atmosphere within a temperature range of not lower than a melting point of the aluminum powder and lower than 700° C.; and removing the supporting powder from a sintered body. With this method, the porous aluminum having a high porosity and a uniform pore diameter, which is suitable for a current collector in a lithium-ion secondary battery and for a variety of filters, is readily manufactured.
