Quantitative Diagnosis of Li Plating Morphology by Analyzing Response of Electrochemical Impedance Spectroscopy in Working Li Batteries
reduction (LGF > 2.0) due to their large electrochemically active surface area (ECSA), while compact spherical or nodule-like Li showed gradual changes (LGF < 1.7). The established methodology provides both fundamental insights into Li deposition processes and a practical tool for battery safety monitoring, offering significant potential for optimizing fast-charging protocols and improving battery management systems.
