Electrolytic copper foil with high temperature dimensional stability and texture stability and method for producing the same |
abstract |
The invention relates to an electrolytic copper foil and a manufacturing method thereof. The electrolytic copper foil has high dimensional stability and texture stability in a high temperature environment of a manufacturing process of a lithium secondary battery. The thermal expansion coefficient of the electrodeposited copper foil of the present invention in the temperature range of 30-190° C. is 17.1-22 μm/(m·° C.), and the change rate of the full width at half maximum of the (220) plane after heat treatment at 190° C. for 30 minutes is 0.81‑1.19, and the weight deviation in the transverse direction is 5% or less. |
