Title:
METAL FOIL FOR CURRENT COLLECTOR OF SECONDARY BATTERY AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO/2004/025758
Kind Code:
A1
Abstract:
A metal foil for the current collector of a secondary battery satisfying the following relations; 4.9×108≤T×S×Y≤31×108, and 4.5≤&epsiv -(0.0005×T2)≤15 assuming the thickness (T) is 8-40µm, the breaking strength is (S, MPa), the breaking elongation is (&epsiv , %) and the Young’s modulus is (Y, MPa). This foil is preferably a nickel foil and can be produced by softening a metal foil produced by an electrolytic deposition method. A metal foil for the current collector of a secondary battery exhibiting excellent carrying performance of active substance and electric conductivity can thereby be obtained.
