Abstract
An electrolytic copper foil for a lithium secondary battery, which is applied as a negative electrode current collector of a lithium secondary battery, wherein when a correlation between a thermal treatment temperature of the electrolytic copper foil for a lithium secondary battery, which corresponds to a variable x, and an elongation increment ratio of the electrolytic copper foil for a lithium secondary battery, which corresponds to a variable y, is expressed as y=ax+b (100≤x≤200) on an x-y two-dimensional graph, the 'a' value is in the range of 0.0009 to 0.0610.
