Aromatic and aliphatic N-heterocyclic chemical salts were synthesized by counter-anion-exchange reactions after substitution in order to apply them as organic electrolyte supporters an electrochemical capacitor (super capacitor). The aromatic N-methylpyridinium tetrafluoroborate ([MPy]+[BF4]−), hexafluorophosphate ([MPy]+[PF6]−), 1,3-dibuthylimidazolium ([DI]+[BF4]−), ([DI]+[PF6]−), 1-buthyl-4-...
