DEVICE FOR INSPECTING FOR ELECTRODE ASSEMBLY DEFECTS BEFORE ELECTROLYTE INJECTION AND DEFECT INSPECTION METHOD THEREFOR

An apparatus for inspecting a failure of an electrode assembly before injecting an electrolyte of the present technology includes a short-circuit tester configured to detect a short circuit of the electrode assembly by applying a predetermined voltage to a positive electrode and a negative electrode of the electrode assembly; a multimeter electrically connected to the short-circuit tester and configured to measure a voltage and a current of the electrode assembly over time; and a failure determination part connected to the multimeter and configured to monitor changes in voltage and current measured by the multimeter and determine a type of a failure of the electrode assembly from data on the changes in voltage and current over a predetermined period of time. A method of inspecting a failure of an electrode assembly before injecting an electrolyte of the present technology includes measuring a voltage and a current of the electrode assembly over time by applying a predetermined voltage to a positive electrode and a negative electrode of the electrode assembly; and determining at least one failure type from among a false failure, a bridge failure, and a spot failure from data on changes in voltage and current over a predetermined period of time.
