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.
Supercapacitors as energy storage could be selected for different applications by considering characteristics such as energy density, power density, Coulombic efficiency, charging and discharging duration cycle life, lifetime, operating temperature, environment friendliness, and cost.
These capacitors exhibit extremely low ESR and equivalent series inductance, coupled with high current-handling capabilities and outstanding high-temperature stability. As a result, they show immense potential for applications in electric vehicles, 5G base stations, clean energy generation, smart grids, and other fields.
Capacitors possess higher charging/discharging rates and faster response times compared with other energy storage technologies, effectively addressing issues related to discontinuous and uncontrollable renewable energy sources like wind and solar .
In comparison to batteries, supercapacitors exhibit a superior power density and the ability to rapidly store or discharge energy . Nevertheless, their energy density is lower due to the constraints associated with electrode surface charge storage.
When compared to traditional capacitors, they possess a lower power density but a higher energy density . Supercapacitors can serve as rapid starting power sources for electric vehicles, as well as balancing power supplies for lifting equipment.
