I use GPES software in Autolab instrument. when i set cut off in chronopotentiometery to investigate charge/discharge of supercapacitor, the potential not receive to the determined cut off. how can find the correct time and potential cut off to put the software items?
can i take this information from cyclic voltmetery?
is potential range of the chronopotentiometery graph should be similar to the cyclic voltametery potential windows?
it will be kind of you, if you can help me
Try to increase the (manual) Current range, and/or the Current value[1].

Hi Hani Sayahi, the laboratory where I do my research also uses the GPES and ANOVA software in the Autolab instruments, the potential windows that we adopt in the galvanostatic charge-discharge analyzes are the same as the ones we carry out in the cyclic voltammetry tests, because by the technique of cyclic voltammetry we check the redox peaks (when there is) of the materials used in a supercapacitor, also what can be interesting is to adjust the current density in which you can use in your tests. However, when we align the windows of potentials used in the galvanostatic charge-discharge with those adopted in cyclic voltammetry, I find no problems. I hope I collaborated with You
Dear João Carlos Martins da Costa
Thanks for your time and advices. I will check it.
