I prepared Ag-deposited material on V2O5 graphene and tried to use KOH as electrolyte. However, the resulting CV pattern does not seem to have good symmetry. Can someone suggest which electrolyte I use for this composite material.
Hello Han-Ching Jao ,
Firstly can you specify the potential range that you wish to use and the reference electrode?

Hello Jules Lloyd Hammond ,
The reference electrode I use is Ag/AgCl and I hope to use it in the water system electrolyte , potential range between -1~1.
Remark： I want to use on supercapacitor.
Yes, I just found your CV plot within the .xlsx - you have a lot of processes going on. I will attach it for others. Have you checked different scan rates? Is the response stable over time? What scan rate did you use?
I would also avoid using KOH, particularly with an Ag/AgCl electrode.
Of course, electrolyte will affect the overall performance. I would check literature to see what others have used with similar electrode strurctures.
Suggestions for aqeous electrolytes would be KCl, Na2SO4, Li2SO4, KNO3
