<P>PROBLEM TO BE SOLVED: To provide a copper-alloy foil having high adhesion property, to provide an electrode for a lithium-ion secondary battery using the copper-alloy foil, and to provide a method for manufacturing the copper-alloy foil. <P>SOLUTION: The copper-alloy foil is effectively manufactured by performing processing in order by one series of steps of a melting step, a hot-rolling step, a first cold-rolling step, a solution-treating step, a second cold-rolling step and an aging-treating step in this order. The copper-alloy foil contains the total of Cr of 0.01-0.5 wt.% and the balance is composed of Cu and inevitable impurities, and on the surface of the copper-alloy foil, a Cr precipitate exists. <P>COPYRIGHT: (C)2012,JPO&INPIT |
