Electrochemical Impedance Spectroscopy Study with a Blocking Symmetric Cell: Qualitative Analysis for Interface of Electrode-Electrolyte

摘要

Li-ion transport which is the fundamental driving force affects to lithium-ion batteries performance thermodynamically and kinetically. A facile and accurate tool is needed to analyze Li-ion transport affected by the electrode structure and electrolyte. Electrochemical impedance spectroscopy (EIS) is a well-known tool to evaluate a battery system. The actual interface of electrode-electrolyte and Li-ion transport can be confirmed quantitatively by analyzing low frequency region of EIS.
