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.
Electrochemical capacitors are known for their fast charging and superior energy storage capabilities and have emerged as a key energy storage solution for efficient and sustainable power management.
Due to the challenges mentioned aforementioned, batteries alone cannot offer a comprehensive solution for energy storage. Electrostatic capacitors can also be used for energy storage applications. [25 - 29] The power density of electrostatic capacitors is extremely high (≈10 6 –10 7 Wh kg −1).
Electrical energy storage technologies play a crucial role in advanced electronics and electrical power systems. Electrostatic capacitors based on dielectrics have emerged as promising candidates for energy storage applications because of their ultrafast charge-discharge capability and stability (1 – 3).
