Abstract

The impedance behavior of a 3.4 Ah pouch Lithium-Sulfur cell was extensively characterized using the electrochemical impedance spectroscopy (EIS) technique. EIS measurements were performed at various temperatures and over the entire state-of-charge (SOC) interval without applying a superimposed DC current. The obtained results have revealed a high dependency of the pouch cell’s impedance spectrum on the operating conditions. An equivalent electrical circuit was proposed to further analyze the results and to quantify the contributions of different resistances to the total impedance of the Li-S pouch cell at different SOCs and temperatures.
