Abstract
Discussed is an electrode tab disconnection inspection apparatus of a battery cell that can include an impedance measurement part connected to electrode leads of a battery cell to be inspected, and configured to measure an impedance value according to a frequency of the battery cell; and a determination part configured to compare impedance value data according to the frequency of the battery cell to be inspected acquired by the impedance measurement part and a predetermined impedance value data group according to a frequency of normal battery cells having no disconnected electrode tabs or a frequency of tab disconnected battery cells having disconnected electrode tabs to determine whether the electrode leads of the battery cell to be inspected is disconnected.
