| 发明名称 | Electrolytic copper foil | ||
| 摘要 | 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%. | ||

| 主权项 | 1. An electrolytic copper foil, comprising a shiny side and a matte side, each of the shiny side and matte side have a surface roughness of less than 2 μm, the electrolytic copper foil also possessing texture coefficients for each of a (111) surface, a (200) surface, a (220) surface and a (311) surface; wherein based on a total sum of the texture coefficients of the (111) surface, the (200) surface, the (220) surface and the (311) surface of the electrolytic copper foil, a sum of texture coefficients of the (220) surface and the (311) surface of the electrolytic copper foil is greater than 60%, with the proviso that the texture coefficient of the (311) surface is at least 1.36. | ||
