摘要： The present disclosure relates to a copper foil which exhibits surprising anti-deformation properties (e.g., it is resistant to swelling, sagging, and wrinkling). Typically, the copper foil has (a) a shiny side with a surface roughness (Rz) in the range of 0.6 to 1.9 μm; (b) a matte side with a surface roughness (Rz) in the range of 0.6 to 1.9 μm; and (c) a lightness L* value of the matte side, based on the L*a*b* color system, in the range of 12 to 35. The disclosure further relates to an anode comprising an anode active material on an anode current collector, wherein the anode current collector includes the above-mentioned copper foil. The anodes are used in, for example, lithium ion secondary batteries.
