A Rapid Method for Determining the Complete Frequency-Dependent Electrode Impedance Response
Traditionally, capturing the low frequency response of electrodes involves having to capture the entire frequency range of impedance. The most critical impedance element of an electrode typically involves the low frequency response where the electrode polarization resistance is determined. Depending on the electrode and electrolyte, low frequency impedance...
