COPPER FOIL FOR LITHIUM-ION BATTERY COLLECTOR BODY

摘要

Disclosed is a copper foil for a lithium-ion battery collector body, the plate thickness of which is highly precise. A copper foil for a lithium-ion battery collector body has an average surface roughness (Ra) in a rolling parallel direction (Raavg) of 0.01-0.15µm, and ?Ra=Ramax-Ramin is less than or equal to 0.025µm.
