I use iviumsoft for CV and GCD in order to measure electrochemical properties of supercapacitor electrode material.
Let's say that CV curves make pretty large shape in potential window of 0 to 0.6V.
However, in GCD potential does not increase more than even 0.54V VERY OFTEN.
In case that CV curves are very thin around 0.54V, then it makes sense. However, even when CV curves make pretty thick shape up to 0.6V, the problem still occurs.
I wonder what makes the discrepancy of potential window between CV and GCD.
