Abstract

The present disclosure relates to a secondary battery inspection apparatus, a secondary battery inspection method, and a secondary battery manufacturing method, and the problem solved by the present disclosure is to identify an internal state of a secondary battery in a non-destructive manner. A secondary battery inspection apparatus according to one embodiment includes a magnetic field generator configured to apply a magnetic field to the secondary battery to be tested, a high frequency generator configured to generate a high frequency of a predetermined frequency and apply the high frequency to the secondary battery to be tested, a sensor configured to detect electromagnetic waves emitted from the secondary battery to be tested to which the high frequency is applied while the magnetic field is applied and a processor configured to determine an internal state of the secondary battery to be tested using the emitted electromagnetic waves detected by the sensor.
