Electrochemical Impedance Spectroscopy (EIS) has many advantages in comparison with other electrochemical techniques. During EIS experiments, a small amplitude ac signal is applied to the system being studied. EIS is a non-destructive method for the evaluation of a wide range of materials, including coatings, anodized films, corrosion inhibitors, batteries and fuel cells, and can provide... Electrochemical impedance spectroscopy or EIS is a powerful technique for the characterization of electrochemical systems. The promise of EIS is that, with a single experimental procedure encompassing a sufficiently broad range of frequencies, the influence of the governing physical and chemical phenomena may be isolated and distinguished at a

Basics of Electrochemical Impedance Spectroscopy. 10/6/2015. Definition of Resistance and Impedance. Resistance is the ability of a circuit element to resist the flow of electrical current. Ohm's law defines resistance in terms of the ratio between voltage, E, and current, I. While this is a well known relationship, its use is limited to only one circuit element -- the ideal resistor. An ideal... Basics of Electrochemical Impedance Spectroscopy Introduction • It follows Ohm's Law at all current and voltage levels.
