This should be addressed in the text. Moreover, the authors state that the electrode present a good rate capability but the scan rates tested were limited to 20mV/s, a rather low value. It would be interesting to see what would be the behavior of the material with higher scan rates. 2) The statement of page 9 line 16 is not clear. In fact, in the case of Warburg impedance the higher the slope the more difficult is the process - in the present case the slope is not vertical so I agree that ion diffusion/adsorption could occur swiftly. However the statement is unclear. 3) In Figure 5b, the authors present the values of capacitance, determined from the given equation, for different values of frequency. However, as stated previously, at low frequencies a Warburg behavior is observed and therefore the values of capacitance determined between 10-1and 10-2 are obviously meaningless, as in this frequency range the process that is occurring is diffusion. 4) The reasons presented by the authors to explain the differences in capacitances values obtained from EIS and GCD methods are also very controversial. In fact, the two techniques are different and different information is obtained from each one. First, the potential at which the impedance spectra were acquired is missing. In fact the reasoning presented would only make sense if the experiments were conducted at a potential where the redox process were active, otherwise only charging/discharging of the double layer would be observed. Moreover, this capacitive behaviour is not evident form the Nyquist plots alone, especially in the case of NiO. Bode plots should be provided to clear this point (see for example Electrochimica Acta Volume 167 (2015) 13-19). Also, the degree at which the samples are polarized in both methods is totally different making difficult comparison between them. This text concerning impedance analysis should therefore be completely revised. 5) Finally the authors should improve the English namely by avoiding the very long and confusing sentences. |
