Abstract
A method and an apparatus for evaluating a battery cell. The battery cell may include a hermetically sealed outer casing, a plurality of electrically conductive components enclosed within the outer casing, an electrically conductive terminal having a proximal end that extends within the outer casing and a distal end that extends in a longitudinal direction relative to the battery cell outside the outer casing, and a solid electrical and mechanical joint formed between one or more of the electrically conductive components and the proximal end of the electrically conductive terminal. Evaluation of the battery cell may include measuring the impedance of the battery cell while applying a longitudinal pulling force or a transverse bending force to the electrically conductive terminal and the solid electrical and mechanical joint.
