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.
Nowadays, these storage devices are widely used in gadgets such as laptops, digital cameras, space emergency doors, mobile phones, aircraft, electric vehicles (EVs), and hybrid electric vehicles (HEVs) [9, 10 ]. Fig. 1 depicts a comparison of all the electrochemical storage devices in terms of power and energy densities via the Ragone plot.
Miniaturized energy storage is essential for the continuous development and further miniaturization of electronic devices. Electrochemical capacitors (ECs), also called supercapacitors, are energy storage devices with a high power density, fast charge and discharge rates, and long service life.
4. Future Outlook Emerging research areas in energy storage are focusing on advanced materials like solid-state batteries and exploring innovative concepts such as the development of advanced electrode materials, characterized by higher surface area and conductivity.
