Apparatus For Inspecting Electrode Current Collectors, Electrode Manufacturing Apparatus, And Electrode Manufacturing Method

Abstract: An apparatus for inspecting electrode current collectors, according to the present invention, comprises: a data collection unit for collecting, above an electrode current collector between a plurality of transfer rollers for transferring or stopping the electrode current collector in the longitudinal direction, half-width data of the (hkl) plane by XRD-analyzing the electrode current collector in a stationary state; and a selection unit for selecting, by using the data, electrode current collectors having a potential density difference (a) of 0.20 or less, which is defined by equation 1. [Equation 1] In equation 1, A (hkl) is the half width of the (hkl) plane of a reference electrode current collector, in which A (111) = 0.089, A (200) = 0.102, A (220) = 0.113, and A (311) = 0.138, and B (hkl) is the half width of the (hkl) plane of an electrode current collector to be inspected.
