摘要:
An object of the present invention is to provide a method for manufacturing a copper foil for a negative electrode current collector (specifically, copper foil for a negative electrode current collector of a lithium ion secondary battery) more excellent in discoloration resistance to improve charge/discharge cycle life of a secondary battery. To achieve the object, a method for manufacturing a copper foil for a negative electrode current collector of a secondary battery subjecting the copper foil to rust-proofing treatment, the method characterized in that the copper foil is rust-proofing treated with a chromate-treatment solution having pH in the range from 3.5 to 7.0 to form a chromate film on the surface of the copper foil is employed.
