The theoretical specific capacitance can be calculated by using the formula, Sp.capacitacne = (F*n) / (m*U).
Where, F is faradaic constant
n is no.of electrons involved in the electrochemical reaction per atom
m is atomic mass of the electrochemical system
and, U is the potential window.
My doubt is whether this calculated Sp.capacitance in only due to faradaic process or both from faradaic and non-faradaic processes???
Artur is right on EDLC.
In addition, even for those materials with pseudocapacitance, the equation you have described may still not apply because the n value is highly likely different when the same material is used in a battery or supercapacitor. In supercapacitor, to maintain the capacitive behaviour (i.e. rectangular CV and linear GCD), the n value is usually a fraction of that for battery in which the material behaves in the conventional Faradaic manner (i.e. peak-shaped CV and non-linear GCD) and can be described, at least approximately or broadly, by the Nernst equation.
Dear Artur and George,
Thank you very much for your answers.
Can you please suggest me any papers or books where \i can get to know more about it???
You may read my recent review article which is free to download. This paper does contain some basic science about supercapacitor.
