Hi,
Can anyone help me,
I want know, which materials can we use as electrolytes in Supercapacitors other than Potassium hydroxide and Sulfuric acid. For better power density or energy density.
That is an alternative (ethylene carbonate/dimethyl carbonate mixture (50:50 w/w) containing 1 M LiPF6 salt (J Appl Electrochem (2014) 44:105–113) for lithium intercalation. You can just remove the lithium salt if you want to. But definitely there are several others possibility.
i suggest you to choose electrolyte ions which is very smaller size ,since smaller ions can easily penetrate into the electrode material.
Larger Charged ions are freely moving on electrolyte but not on electrode materials.So in order to improve the capcitor performance you should choose electrolyte which have high wettablity ,of course smaller ions will have high wettablity.Even if you are using KOH ,you can use some external pressure to the electrode so that you can improve the wettablity on the electrode surface.
External pressure can be applied by pressing the two electrode with electroyte in between the electrode i.e on seperator.
