Abstract
An eddy current non-destructive evaluation system for an electrode film material includes: at least one control module configured to generate a transmission signal; and a first pair of coils. The first pair of coils includes: a first coil disposed adjacent the electrode film material and configured to operate in a transmit mode, and, based on the transmission signal, to generate an electromagnetic field that passes through the electrode film material; and a second coil disposed adjacent and on an opposite side of the electrode film material as the first coil and configured to operate in a receive mode. The second coil is configured to generate a electromagnetic field voltage based on the electromagnetic field. The at least one control module is configured, based on the electromagnetic field voltage, to at least one of determine a thickness of the electrode film material and detect a defect of the electrode film material.
