Abstract

An apparatus for inspecting an electrode current collector according to the present invention includes a data collection unit, which is on an electrode current collector between a plurality of transfer rollers for transferring or stopping the electrode current collector in a longitudinal direction, and configured to perform XRD analysis on the electrode current collector in a stationary state to collect full-width-of-half-maximum data of a (hkl) plane, and a selection unit configured to select an electrode current collector having a potential density difference (α) of 0.20 or less as defined by Equation 1 below by using the above data. α=A111−B111A1112+A200−B200A2002+A220−B220A2202+A311−B311A31124In Equation 1 above, A(hkl) is a full width of half maximum of a (hkl) plane of a reference electrode current collector, wherein A(111)=0.089, A(200)=0.102, A(220)=0.113, and A(311)=0.138, and B(hkl) is a full width of half maximum of a (hkl) plane of an electrode current collector to be inspected.
