Title:

COLLECTOR ALUMINUM FOIL, SECONDARY BATTERY, AND EVALUATION METHOD

Document Type and Number:

WIPO Patent Application WO/2015/033525

Kind Code:

A1

Abstract:

The mechanical strength of an electrode sheet becomes problematic when employing means for improving the productivity of an electrode process. In a collector aluminum foil of the present invention, when the intensities of the (022) and (111) diffraction peaks appearing in an XRD spectrum measured in the reflection geometry are denoted by IB(022) and IB(111), respectively, a value of IB(022)/IB(111) is 200 or less.
