Abstract
Surface-treated copper foils comprising an electrodeposited copper foil including a drum side and a deposited side are reported. The treatment layer is disposed on one of the drum side and the deposited side and provides a surface-treated side. The treatment layer comprises a nodule layer and the surface-treated side exhibits a void volume (Vv) in a range of 0.1 to 0.9 μm/μm. The surface-treated copper foil also has a combined hydrogen and oxygen content of less than or equal to 300 ppm.
