For each frequency an impedance is determined and plotted (real v. imaginary components). From the plot the corroding system is modeled by an electrical circuit and the corrosion rate of the system ...

Determining the current state-of-health (SOH) of the battery on board of a vehicle is still a challenging task. Electrochemical Impedance Spectroscopy (EIS) is an established laboratory method for the ...

With electrochemical impedance spectroscopy (EIS), corrosion and electrochemical instruments apply small amplitude signals over a range of frequencies and record both the resistance and capacitance ...
