Faradaic impedance is the resistance and capacitance acting jointly at the surface of an electrode of an electrochemical cell, and has emerged as the basis for an important technique in a form of spectral analysis applicable to a wide variety of materials where the technique depends on the capacitive component of faradaic impedance.
In electrochemistry, faradaic impedance is the resistance and capacitance acting jointly at the surface of an electrode of an electrochemical cell. Over the past two decades faradaic impedance has emerged as the basis for an important technique in a form of spectral analysis applicable to a wide variety of materials. This technique depends on the capacitive component of faradaic impedance.
