electrical energy storage is one of the great needs of today's world and various tools for energy storage are presented in different dimensions with varying efficiency.the tools on electrochemical basis of electrochemistry, battery and ultracapacitor are one of the most effective tools for storing
electric energy in small dimensions. the energy density and the battery capacity are highly dependent on the electrode material, which is why it is important to develop the electrode material.recently, ion fluid has been used as electrode material. Ionic liquids have recently been
used as electrodes for supercapacitors. In this thesis, two graphene mixtures functionalized with diazobic cyclo [2,2,2] octane and tungstate ionic liquid (GO@Fe3O4@IL/W) and ionic liquid [Caff-TEA] + [ZnBr3] - Used as supercapacitor electrode.Electrochemical analyzes of open-circuit voltage, cyclic voltammetry, impedance spectral analysis, and charge-discharge cycle were used to investigate the performance of these two materials in a three-electrode system.And according to the results, the specific capacitance of GO @ Fe3O4 @ IL / W was obtained at the current density of 0.2 Ag-1, 332.45 Fg-1 and at the current density of 0.5 Ag-1, 230.75 Fg-1. Maintains 80% of its initial capacity after 1500 cycles. Special Capacity of [Caff-TEA] + [ZnBr3] - At current
density of 1Ag-1, was obtained 165.28Fg-1 and was able to retain 80% of its initial capacity after 7000 cycles, a significant number for this Bunch of compounds. Compared to the results reported in the literature, these two combinations can be acceptable alternatives for supercapacitor use.
