P=E/t, or P=V2 /(4ESR).................... So will Rct influence the specific power ?
And more over most activated carbon electrodes reported in the literature have Rct? Where did they get Rct from, when they report to have pure EDLC?! What is that semi circle in the Nyquist plot actually depicting in this case?

Hi Dr. Geletii,
Most supercapacitor electrodes show a semi-circle at the high frequency region in the Nyquist plot. This semi-circle is mostly attributed to the charge transfer. However, for pure carbon-based electrodes there would be no charge transfer (?-?). But still Nyquist plot would have semi circle at the high frequency end. So why do we get this semicircle even when we dont have charge transfer?
