How do you perform electrochemical impedance spectroscopy?
Electrochemical impedance is usually measured by applying an AC potential to an electrochemical cell and then measuring the current through the cell. Assume that we apply a sinusoidal potential excitation. The response to this potential is an AC current signal.
How do you do EIS experiment?
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.
What is EIS testing?
Electrochemical Impedance Spectroscopy (EIS) is a well-established quantitative method for the accelerated evaluation of the anti-corrosion performance of protective coatings. Within short testing times, EIS measurements provide reliable data, allowing for the prediction of the long-term performance of the coatings.
What do we measure in Electrochemical Impedance Spectroscopy?
Electrochemical Impedance Spectroscopy (EIS) is an electrochemical techniques to measure the impedance of a system in dependence of the AC potentials frequency.
How do you plot EIS data?

- Copy Z and -Z’ values, open origin software and paste them on respective columns.
- Then, select the two columns, plot them as Line + symbol type.
- You will get the Nyquist plot, which containing-Z on Y axis and Z on X-axis.
What is EIS used for?
Electrochemical Impedance Spectroscopy (EIS) is an electrochemical technique with applications in corrosion, biosensors, battery development, fuel cell development, paint characterization, sensor development, and physical electrochemistry. EIS can even be used to test the freshness of fish!
What is the purpose of impedance spectroscopy?
What do you need to know about electrochemical impedance spectroscopy?
Figure 1 is an electrochemical impedance spectroscopy (EIS) measurement system for characterizing lith- ium ion (Li-Ion) and other types of batteries. EIS is a safe perturbation technique used to examine processes occurring inside electrochemical systems. The system measures the impedance of a battery cell over a range of frequencies.

How is the response voltage measured in EIS?
EIS measurements are ratiometric. To measure an unknown impedance (ZUNKNOWN), an ac current signal is applied across the known resistor, RCAL, and the response voltage, VRCAL, is measured. Next, the same signal is applied across the unknown impedance, ZUNKNOWN, and the response voltage, VZUNKNOWN, is measured.
