Synthesis of Aromatic and Aliphatic N-Heterocyclic Salts and Their Application as Organic Electrolyte Supporters in Electrochemical Capacitor

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-methyl-1,2,4-triazolium ([BMTA]+[BF4]−), ([BMTA]+[PF6]−). N,N-dimethylpiperilidium ([DMP]+[BF4]−), ([DMPy]+[PF6]−), N,N-dimethylpyrrolidium ([DMPy]+[BF4]−) 1-ethyltriethamine ([E-TEDA]+[BF4]−), ([E-TEDA]+[PF6]−), respectively. We confirmed the successful synthesis of 1H-NMR, FT-IR, GC/MS analysis before conducting reactions. Then, we determined potential vanadium acetylacetonate (V(acac)3) under acetonitrile presence energy-storage chemicals. By cyclic voltammetry, maximum voltages with reached 2.2 V a fixed current value. Charge-discharge experiments performed anion-exchange membrane using non-aqueous prepared salt acetonitrile.
