Interactions between Graphene and Ionic Liquid Electrolyte in Supercapacitors
The graphene material prepared by the chemical reduction method usually has oxygenic functional groups in it and such functional groups often result in interactions between the graphene electrode and the electrolyte in supercapacitors. We have examined the existential form of interactions between graphene as the electrode and three kinds of ionic liquid, 1-ethyl-3-methylimidazolium bis (trifluo...
متن کاملHigh voltage supercapacitors based on carbon-grafted NiO nanowires interfaced with an aprotic ionic liquid.
The report provides a preliminary assessment of the charge storage prerogatives of an asymmetric electrochemical capacitor employing a carbon-grafted NiO electrode interfaced with 1-ethyl-3-methyl imidazoliumdicyanamide as an ionic liquid electrolyte. This configuration has been demonstrated to be potentially exploited for developing hybrid supercapacitors providing as high energy density as 21...
متن کاملTwo-dimensional NiCo2O4 nanosheet-coated three-dimensional graphene networks for high-rate, long-cycle-life supercapacitors.
We report the synthesis of two-dimensional (2D) NiCo2O4 nanosheet-coated three-dimensional graphene network (3DGN), which is then used as an electrode for high-rate, long-cycle-life supercapacitors. Using the 3DGN and nanoporous nanosheets, an ultrahigh specific capacitance (2173 F g(-1) at 6 A g(-1)), excellent rate capability (954 F g(-1) at 200 A g(-1)) and superior long-term cycling perform...
متن کاملImproved Performance of Ionic Liquid Supercapacitors by using Tetracyanoborate Anions
Supercapacitors are energy storage devices designed to operate at higher power densities than conventional batteries, but their energy density is still too low for many applications. Efforts are made to design new electrolytes with wider electrochemical windows than aqueous or conventional organic electrolytes in order to increase energy density. Ionic liquids (ILs) with wide electrochemical st...
متن کاملMagnetic graphene oxide modified by chloride imidazole ionic liquid for the high-efficiency adsorption of anionic dyes
Magnetic graphene oxide modified with 1-amine-3-methyl imidazole chloride ionic liquid (LI-MGO) was prepared through chemical co-precipitation and modified using 1-amine-3-imidazolium chloride ionic liquid. The as-prepared LI-MGO was characterized using X-ray diffraction (XRD), transmission electron microscopy (TEM) and Fourier transform infrared spectrometry (FT-IR). The adsorption properties ...
