But, EC or supercapacitor can provide very high power density with lower energy storage (energy density) than batteries. Troubleshooting and maintaining batteries may be a challenge [15] . Consequently, supercapacitors are predominantly suitable for applications, where the significant power is mandatory for a short period of time.
Highlights. •. Supercapacitors have interesting properties in relation to storing electric energy, as an alternative to batteries. •. Supercapacitors can handle very high current rates. •. Supercapacitors have low energy density to unit weight and volume. •. The price per unit of energy (kWh) is extremely high.
SCs offer several advantages over conventional capacitors and batteries, including a longer cycle life owing to their faster charging-discharging time, reversible charge storage mechanism at the surface, and higher power density [15].
In a supercapacitor, electrode material has a deep connection between the type of supercapacitor as the electrode materials play a vital role in deciding the energy storage mechanism of the system.

A supercapacitor mainly consists of two electrodes, an electrolyte, and a separator within an enclosure that provides the stability of the device protecting it from the external environment. 32 There are many architectures for a supercapacitor, such as 3D (cylindrical, coin cell type, bulk stacked devices, etc.), 2D planner (micro

Working Principle of Supercapacitors A supercapacitor operates by storing electrical energy between two electrostatic double layers created by the formation of thin charge layers on the electrolyte-electrode interface. Because the capacitance value of a capacitor is always exactly proportional to the surface area of its conduction plates,
It should be noted that the failure mechanism mainly depends on the energy storage mechanism, which is dominated by the composition of SCs. This makes the difference among different types of SCs (i.e. EDLCs, PCs, and HSCs), and even among those ones belonging to the same type but consist of different electrode and electrolyte
