Title:
耐屈曲性に優れた二次電池用電解銅箔及びその製造方法
Document Type and Number:
Japanese Patent JP7061120
Kind Code:
B2
Abstract:
The present invention relates to an electrolytic copper foil for a secondary battery, having excellent flexural resistance, and a method for producing the electrolytic copper foil and, more specifically, to an electrolytic copper foil for a secondary battery, which has excellent flexural resistance even without the use of many additives in a copper electrolyte when producing a copper foil, and to a method for producing the electrolytic copper foil. The electrolytic copper foil for a secondary battery according to the present invention is an electrolytic copper foil for a secondary battery, which is produced from a plating solution, containing total organic carbon (TOC), cobalt and arsenic, by using a drum and is coated with a cathode active material, wherein the ratio between the TOC, cobalt and arsenic contained in the electrolytic copper foil follows the following formula 1: [Formula 1] TOC / (cobalt + arsenic) = 1.30 - 1.55.
