Abstract
A method for validating non-destructive, electromagnetic methods in atmospheric conditions of a battery cell intended to include a lithium metal layer includes selecting a lithium mimic metal layer to replace the lithium metal layer; and creating a mock-up sample including one or more layers of the battery cell. One or more layers comprise the lithium mimic metal layer. The method includes performing electromagnetic testing of the mock-up sample.
