Title:

ALUMINUM ALLOY FOIL FOR ELECTRODE COLLECTOR, METHOD FOR MANUFACTURING SAME, AND ELECTRODE MATERIAL

Document Type and Number:

WIPO Patent Application WO/2013/176038

Kind Code:

A1

Abstract:

Provided are: an aluminum alloy foil for electrode collectors which allows for thin rolling during the manufacture of the aluminum alloy foil, and which makes it possible to ensure a strength that is sufficient to prevent breakage during the active material paste-coating step and wrinkling during the pressing step, and that is suitable for the series of manufacturing steps from the manufacture of the aluminum alloy foil to the manufacture of an electrode material; a method for manufacturing same; and an electrode material. In the present invention, an aluminum alloy foil for an electrode collector, a method for manufacturing same, and an electrode material are provided, the aluminum alloy foil being characterized in containing Mn: 0.50 to 1.50 mass% (hereinafter mass% is written simply as %), Cu: 0.05 to 0.50%, Fe: 0.20 to 1.00%, and Si: 0.01 to 0.60%, with the remainder being Al and unavoidable impurities, wherein the solid solution content of Mn is 1500 ppm or more, the solid solution content of Cu is 40 ppm or more, and the tensile strength (T1) after final cold rolling is 260 MPa to 350 MPa, inclusive.
