8 compares a potentiostatic EIS to a galvanostatic EIS scan. Because they are practically coincident, we can conclude that either method works for this system. The lower graph in Fig. 8 shows the potential-dependency of potentiostatic EIS for three different open-circuit potentials. Fits (...
while the bottom shows the evolution of the potentiostatic EIS Nyquist plot during the discharge. Fig. 4 reveals that potentiostatic EIS and galvanostatic EIS show the same result in the whole range of frequencies, for both experimental conditions. The fact that these results are practically...

Electrochemical properties were studied by electrochemical impedance spectroscopy (EIS). The electrochemical and supercapacitive properties of MnOthin films have been studied in 1 M NaSOelectrolyte. The maximum supercapacitance has been observed for 1.6 V/Ag/AgCl....
The most extensively used electrochemical technique for the evaluation of the concentration of analytes and the measurement of resistance over the electrode in an aqueous solution is termed electrochemical impedance spectroscopy (EIS). Among these techniques, EIS has been utilized by several researchers fo...
The electron transfer rates of the three samples were analyzed by EIS. Fig. 6 presents the Nyquist plots of S1, S2, and S3 at −200 mV versus RHE. The charge-transfer resistance (Rct) and electrolyte solution resistance (Rs) were obtained by fitting the plots using a simplified Randles ...
