Title:
ELECTROLYTIC COPPER FOIL FOR SECONDARY BATTERY ANODE COLLECTOR AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2012/133564
Kind Code:
A1
Abstract:
The objective of the present invention is to provide: an electrolytic copper foil that is for a secondary battery anode collector and that has superior extensibility that can withstand changes in expansion/contraction at minute units while having high strength; and a method for producing the foil. Specifically, the electrolytic copper foil for a secondary battery anode collector has a tensile strength of 45-70 kg/mm2 in the apparent stress-strain curve, the value of the tensile strength is greater than the value of the breaking stress, and the degree of extension is at least 5%.
