Document Type and Number:
Japanese Patent JP6975782
Kind Code:
B2
Abstract:
The present invention relates to an electrolytic copper foil for a secondary battery and a method of producing the same, and more particularly, to an electrolytic copper foil for a secondary battery, which has little change in a physical property of a copper foil before and after vacuum drying in a process of producing an electrolytic copper foil, thereby exhibiting excellent cycle life in a battery test at a high-density negative electrode, and preventing cracking, and a method of producing the same. According to one aspect of the present invention, exemplary embodiments of the present invention include an electrolytic copper foil for a secondary battery produced from a plating solution containing Total Organic Carbon (TOC), zinc, and iron by using a drum, in which a ratio of the TOC to the zinc and the iron contained in the electrolytic copper foil follows Formula 1 below:
