Why is electrochemical impedance spectroscopy used in battery research?
Electrochemical impedance spectroscopy has a history of successful use in battery research as well as much potential for future studies. To understand why EIS is peculiarly capable of analyzing various batteries, the fundamental electrochemical processes present in a battery system must be understood.
Do all components contribute to the impedance response of a battery?
