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.
3. Supercapacitors Supercapacitors, also known as Electric Double-Layer Capacitors (EDLCs)or ultra capacitors, have a high energy density when compared to conventional capacitors, typically thousands of times greater than a high capacitance electrolytic capacitor.
In comparison to various electrical storage devices like batteries, dielectric capacitors possess the capability to discharge stored energy in an extremely brief timeframe (microseconds), resulting in the generation of substantial power pulses .
However, in many BEV applications the required power is the key factor for battery sizing, resulting in an over-dimensioned battery pack [4, 5] and less optimal use of energy . These shortcomings could be solved by combination of battery system with supercapacitors [6 – 8].
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 .
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 .
