Magnitude of oxidation and specific capacitance of the NiO film. Magnitude of oxidation (S1): interpolation of experimental data from the literature to calculate the parabolic rate constant Log Kp (Figure S1) and calculation of weight gain per unit area M (Table S1). Specific capacitance of NiO-Film (S2): the specific capacitance of the supporting NiO film is measured at different scan rates (Figure S2) to estimate the maximum contribution of the supporting NiO film.
