An electrolytic copper foil, which is particularly suitable for the application of a lithium ion secondary battery, has a shiny side and a matte side with a roughness of less than 2 μm. Based on the total sum of the texture coefficients of a (111) surface, a (200) surface, a (220) surface and a (311) surface of the electrolytic copper foil, the sum of the texture coefficients of the (220) surface and the (311) surface of the electrolytic copper foil is greater than 60%. |
