“…In addition, the existence of Ni 2+ is proved by the binding energy difference of 17.77 eV between Ni 2p 1/2 and Ni 2p 2/3 . In the C 1s spectra (Figure c), the peak at 284.81 eV belongs to sp 3 C–C and 288.72 eV represents CO band. , In Figure d (the O 1 s spectra), the Ni–O band is revealed by the peak at 531.79 eV and the peak at 532.80 eV is originated from O element in PTA . The results of XPS further proves the existence of Ni-MOF/NC, which was consistent with the XRD analysis.…”

Ni-metal–organic framework (MOF)/nano carbon (NC) electrode materials were synthesized by a one-step hydrothermal method. The prepared Ni-MOF/NC presented in the form of NC distributed uniformly on the Ni-MOF sheets, which effectively increased the specific surface area of the material and the rate of redox reaction. The Ni-MOF/NC electrode delivered 828 F/g at 1 A/g. In addition, the asymmetric supercapacitor (ASC) assembled by Ni-MOF/NC and active carbon retained 100% of specific capacitance after 5000 cycles. Furthermore, the ASC delivered energy density of 23.84 W h/kg at 849.74 W/g.

A chromium-based low-cost metal−organic framework (MOF) cathode, MIL (Mateŕiaux de l′Institut Lavoisier)-53(Cr), is coupled with a bioderived porous carbon (BPC) anode, produced from abundantly available agricultural waste betel nut shells in an asymmetric supercapacitor, for the first time. The impact of the electrolyte on the electrochemical behavior of an asymmetric BPC//MIL-53(Cr) supercapacitor was assessed by constructing cells with the following electrolytes: proton-conducting camphorsulfonic acid (CSA), Li + -ion-conducting solutions of LiClO 4 , Na + -ion-conducting sodium poly(4-styrene sulfonate) solution, and ionic liquid (IL:1-butyl-1-methyl-pyrrolidinium trifluoromethanesulfonate)-based solutions. The aqueous H + -ion-based CSA electrolyte shows a superior ionic conductivity (270 mS cm −1 ) and an enhanced transport number (0.96), carries larger ionic currents, and retains high conductivity even at subambient temperatures, clearly outperforming all the other Li + /Na + /IL electrolytes. The BPC/aqueous CSA or LiClO 4 /MIL-53(Cr) supercapacitors show enhanced storage performances, with the H + cell having a specific capacitance of 70 F g −1 and energy and power density maxima of 9.7 Wh kg −1 and 0.25 kW kg −1 and enduring 10 4 cycles. A detailed account of the dependence of the electrolyte cation/ anion-and solvent-type on electrochemical charge storage provides a basis for adapting these design principles to developing highperformance MOF-based supercapacitors.

Metal-organic frameworks (MOFs), owing to their tunable porosity, high surface area, and diversity were investigated as potential supercapacitor materials. PANI/Ni-MOF, a nanocomposite of Ni-MOF and polyaniline (PANI), was fabricated by in situ solvothermal synthesis of Ni-MOF in the presence of the as-obtained PANI. The prepared products were studied using FT-IR, PXRD, SEM, and EDS-mapping techniques. EDS-mapping results exhibited the uniform dispersion of Ni-MOF into the polymeric matrix. Electrochemical properties of the pure Ni-MOF and PANI/Ni-MOF were investigated through CV (cyclic voltammetry), GCD (galvanostatic charge/discharge), and EIS (electrochemical impedance spectroscopy) methods in a three-electrode system. The as-fabricated PANI/Ni-MOF nanocomposite exhibited outstanding electrochemical performance owing to the synergistic effects of PANI with proper conductivity and the Ni-MOF’s porous structure, obtaining an excellent specific capacitance of 601 F g− 1 at 1 A g− 1. Additionally, this supercapacitor material showed a remarkable cycle life after 5000 charge/discharge test, 99.5 % retention of its specific capacitance. These excellent properties would make PANI/Ni-MOF nanocomposite as a proper candidate for supercapacitor electrode material. .
