a Electrical equivalent circuit for fitting the EIS parameters from Nyquist plot (Additional file 1: Figs. S2, S3 of the supplementary document). b Determination of electrode resistivity using the four-point probe method: A is the multimeter for current measurement, V is the multimeter for voltage measurement s = 9.4 mm is the distance between the probes, and t is the thickness of the electrode. 1, 2, 3, and 4 represent the probes
