Synthesis of NiFe-MOF@NiFeTe nanoparticle-rod heterostructure on nickel foam for high-performance hybrid supercapacitors

Synergistic effect of bimetallic NiCo-MOF on foamed nickel for application in high-performance supercapacitors

“…[1][2][3][4] Although the current sources of new energy (biomass energy, ocean energy, geothermal energy, solar energy, and other renewable energy sources) are not enough to replace the status of fossil energy in human society, energy conversion systems to convert new energy into storable electric energy can effectively alleviate the energy crisis arising from the shortage of fossil fuels. [5][6][7][8] Therefore, the development of energy conversion devices with efficient energy storage functions is of high interest to researchers. 9,10 Energy storage devices fall into three main categories: batteries, capacitors, and supercapacitors.…”

Solvent-Assisted Morphology-Induced Nickel Metal–Organic Framework as a Highly Efficient Electrode for Energy Storage Application

“…Zhang et al, synthesized NiFe-MOF@NiFeTe rod-like morphology on a current collector directly by the simple hydrothermal method. The synthesized electrode shows a better specific capacitance of 1245.2 F g –1 at a current density of 5 A g –1 and 92.3% capacitance retention over 1000 charge–discharge cycles . Salunkhe et al synthesized a bimetallic (Ni/Co) porous MOF by varying metal concentrations using the hydrothermal technique.…”

“…The synthesized electrode shows a better specific capacitance of 1245.2 F g −1 at a current density of 5 A g −1 and 92.3% capacitance retention over 1000 charge− discharge cycles. 30 Salunkhe et al synthesized a bimetallic (Ni/ Co) porous MOF by varying metal concentrations using the hydrothermal technique. The prepared flakes exhibit an energy density of 7.8 W h kg −1 at a power density of 173.07 W kg −1 and maintained 88.4% capacitance retention over 3000 charge−discharge cycles.…”
