What exactly is EIS in electrochemistry and what does it aim to achieve?



Looking to gain some background knowledge over the electrochemical technique of EIS

In: Chemistry

Electrochemical impedance spectroscopy (EIS) is a powerful technique that utilizes a small amplitude, alternating current (AC) signal to probe the impedance characteristics of a cell. The AC signal is scanned over a wide range of frequencies to generate an impedance spectrum for the electrochemical cell under test.
