Dear Vivekanand Vivekanand , is there a Faradaic reaction in a supercapacitor ?

Best regards,

Nicolas

Dear Nicolas Murer

In the case of pseudocapacitor material used as an electrode for supercapacitor or while using redox-based electrolytes, the surface faradaic reactions occur on the electrode-electrolyte interface. If I am not wrong.

I am not sure that you are asking for phase change or change of oxidation state? If oxidation state then it is well explained and available in standard text book, literature as well but for phase change may not possible using CV analysis directly...........

Achchhe Lal Sharma Sir,

I am asking about any phase change if occurs (as phase changes occur in the battery) that we could see or not in cyclic voltammetry of pseudocapacitor/battery material based on the faradaic reaction. If yes, then how?

Actually in battery and capacitors normally, redox (Ox/Red) reaction occur without change of its crystal structure. Therefore, i suggest you to look change of oxidation state rather phase change through CV analysis. The phase change could be checked via different numerous characterization tools.........

Thank you very much Achchhe Lal Sharma Sir for your clarification and suggestion for this doubt. I will try it.
