Abstract
An electrolytic copper foil for a lithium secondary battery, wherein a curl indicator C of the electrolytic copper foil, which is defined as 1.21ΔR+1.12ΔCr+0.01ΔG, is 0 or above and 4.0 or below, where ΔR corresponds to an absolute value of a difference between roughness measured on a first surface of the electrolytic copper foil for a lithium secondary battery and roughness measured on a second surface thereof, ΔCr corresponds to an absolute value of a difference between a chrome-deposited amount of an anti-corrosion layer formed on the first surface of the electrolytic copper foil for a lithium secondary battery and a chrome-deposited amount of an anti-corrosion layer formed on the second surface, and ΔG corresponds to an absolute value of a difference between glossiness measured on the first surface of the electrolytic copper foil for a lithium secondary battery and glossiness measured on the second surface.
