Diagnosis of Electrochemical Degradation in a Large-Format NCM Pouch Cell under Over-Discharge Using EIS and Acoustic Emission

Over-discharge of large-format lithium-ion cells can cause electrochemical and mechanical degradation, leading to safety concerns. This study investigated a 67 Ah NCM pouch cell using electrochemical impedance spectroscopy (EIS), acoustic emission (AE), and X-ray computed tomogra...
