  • Electrolytic copper foil and method for producing the same
    Patent number: 9365942
    Abstract: An electrolytic copper foil is provided. The electrolytic copper foil has a shiny side and a matte side opposing to the shiny side, wherein the difference in roughness between the shiny side and the matte side is 0.5 ?m or less. The electrolytic copper foil has a tensile strength of 45 kg/mm2 or above, and is particularly suitable for applications in a lithium ion secondary battery.
    Type: Grant
    Filed: October 25, 2013
    Date of Patent: June 14, 2016
    Assignee: CHANG CHUN PETROCHEMICAL CO., LTD.
    Inventors: Chen-Ping Tsai, Kuei-Sen Cheng, Chyen-Fu Lin
  • Electrolytic copper foil
    Patent number: 9209485
    Abstract: 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 ?m. 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%.
