Japanese Patent JP7164765
Kind Code:
B2
Abstract:
[Object]An object of the present invention is to provide an electrolytic foil and a battery current collector capable of restraining the risk of breakage and tearing during manufacturing due to reduction in film thickness and further exhibiting sufficient strength and elongation during repetitive charging and discharging of a secondary battery.[Solving Means]An electrolytic iron foil in which the electrolytic iron foil is less than 20 um in thickness, the electrolytic iron foil has a first surface and a second surface, and a value obtained by dividing a three-dimensional surface texture parameter Sv by the thickness is equal to or less than 0.27 in both the first surface and the second surface.
