Electrochemical capacitors, also referred to as supercapacitors, are special types of capacitors possessing fast charging capabilities, long life cycles, and low maintenance costs. As a result, supercapacitors are used in a variety of commercial applications such as emergency backup powers, consumer electronics, and hybrid vehicles.
Electrochemical supercapacitors stand out with their superior capacitance density, surpassing traditional electrolytic capacitors by at least two orders of magnitude. However, the intrinsic slow ion dynamics of electrical double layer effects greatly limit supercapacitors characteristic frequency, constraining their applicability in microsystems.
Instead of bare MOF, its composites with activated carbon, metal oxides, graphitic carbon are preferably used as supercapacitor electrode material to enhance capacitance, specific surface area (SSA), energy density and power density of supercapacitor. They have unique structural properties with high specific surface area.
Electrochemical supercapacitors (SCs), which are based on the electric double layer (EDL) effect, have emerged as a promising alternative, offering significantly higher capacitance densities and the capability for on-chip fabrication 7, 8, 9.
Therefore, careful selection of the most fitting electrolyte is crucial in constructing high performing supercapacitors. Three types of electrolytes are currently available for supercapacitors: aqueous, organic, and ionic liquids (IL s).
To enhance electrochemical performance of supercapacitor, we can use a mixture of aqueous and organic electrolyte [e.g. H2 SO 4, KOH] with some redox active species [e.g. K 3 Fe (CN) 6, KI].
