Electrochemical behaviors of Li-argyrodite-based all-solid-state batteries under deep-freezing conditions

초록

We probe the electrochemical performance of Li-argyrodite-based all-solid-state batteries under deep-freezing conditions (-30 degrees C) using electrochemical impedance spectroscopy. The performance deterioration is mainly caused by the increased interfacial resistances of electrolyte and active materials resulting from the slow kinetics of Li-ion transport in solid materials at low temperatures.
