A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate on the conductors.

To clarify the differences between dielectric capacitors, electric double-layer supercapacitors, and lithium-ion capacitors, this review first introduces the classification, energy storage advantages, and application prospects of capacitors, followed by a more specific introduction to specific types of capacitors. Regarding dielectric
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 merits and demerits of energy storage capacitors are compared with the other energy storage units. The basic need of an energy storage system is to charge as quickly as possible, store maximum energy, and discharge as per the load demand.

E ( r ) dv A coaxial capacitor consists of two concentric, conducting, cylindrical surfaces, one of radius a and another of radius b.
A simple energy storage capacitor test was set up to showcase the performance of ceramic, Tantalum, TaPoly, and supercapacitor banks. The capacitor banks were to be charged to 5V, and sizes to be kept modest. Capacitor banks were tested for charge retention, and discharge duration of a pulsed load to mimic a high power remote IoT system.
Thus, the storage capacitance mainly depends on the size of the metal plates, distance between the plates, and the material type of the dielectric medium used. It can be noted that the energy being stored in a capacitor is directly proportional to the capacity and the square of the applied voltage across the terminals of the electrochemical cell.
The energy storage capacitor bank is commonly used in different fields like power electronics, battery enhancements, memory protection, power quality improvement, portable energy sources, high power actuators, ASDs, hybrid electric vehicles, high power actuators, off-peak energy storage, and military and aerospace applications.
