1. An electrodeposited copper foil comprising a drum side and a deposited side;
wherein each of the drum side and the deposited side of the electrodeposited copper foil have a ten-point average roughness, Rz, in the range of 1.0 μm to less than or equal to 2 μm, and each of the drum side and the deposited side of the electrodeposited copper foil further comprise a chromium coating, wherein the electrodeposited copper foil exhibits a primary weight increase of 105 wt. %, when a primary temperature (T105 wt %) is reached during thermal gravimetric analysis (TGA), wherein the primary temperature (T105 wt %), is in a range of 350° C. to 501° C., and
wherein the TGA comprises heating the electrodeposited copper foil at a rate of 5° C./min and an air flow at a rate of 95 mL/min.
