I have fitted my EIS Nyquist plot using EC lab software. Now I need to calculate the double layer capacitance value. For the element Q (constant phase element), there are two parameters with the units as follows;
For instance,
Q1 = 4.1 e-3 F.s^(a-1)
a1 = 0.775
What is the capacitance value for this fitted data? And how to derive it?
Kindly awaiting for the valuable answers
