Capacitors exhibit exceptional power density, a vast operational temperature range, remarkable reliability, lightweight construction, and high efficiency, making them extensively utilized in the realm of energy storage. There exist two primary categories of energy storage capacitors: dielectric capacitors and supercapacitors.
The energy UC stored in a capacitor is electrostatic potential energy and is thus related to the charge Q and voltage V between the capacitor plates. A charged capacitor stores energy in the electrical field between its plates. As the capacitor is being charged, the electrical field builds up.
Supercapacitor has been evaluated as an energy storage device. Classification of supercapacitors has been discussed.
As a result, these SCs are being widely considered as preferable alternatives for energy storage applications. Flexible solid-state supercapacitor devices typically consist of many components, such as flexible electrodes, a solid-state electrolyte, a separator, and packaging material .
