Abstract
Provided are an electrolytic copper foil, an electrode and a lithium-ion cell comprising the same. The electrolytic copper foil has a first surface and a second surface, which are analyzed by grazing incidence X-ray diffraction (GIXRD), and each have an intensity of a characteristic peak of (111) plane denoted by I, an intensity of a characteristic peak of (200) plane denoted by I, an intensity of a characteristic peak of (220) plane denoted by I, an FWHM of the characteristic peak of (111) plane denoted by W, and an FWHM of the characteristic peak of (200) plane denoted by W. The first and second surfaces each have a ratio of (I+I)/(I+I+I) of 0.83 or more and a value of (W+W) of 0.80° or less. By controlling the features, it can improve the corrosion resistance of the electrolytic copper foil and further increase the safety of the lithium-ion cell.
