Abstract
In one embodiment, the present invention relates to a method of treating metal foil, involving sequentially contacting a metal foil with an acidic solution; placing the metal foil in a nickel treatment bath and applying a current through the nickel treatment bath, wherein the nickel treatment bath contains at least about two plating zones, about 1 to about 50 g/l of an ammonium salt, and about 10 to about 100 g/l of a nickel compound; and applying a nickel flash layer to the metal foil. In another embodiment, the present invention relates to a metal foil treated according to the method described above.
