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.
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 .
Supercapacitors, bridging conventional capacitors and batteries, promise efficient energy storage. Yet, challenges hamper widespread adoption. This review assesses energy density limits, costs, materials, and scalability barriers.
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.
As a result, commercially available supercapacitors typically exhibit energy densities ranging from 1 to 10 Wh/kg, significantly lower than lithium-ion batteries (100–265 Wh/kg) , . The energy density (Wh/kg) and power density (kW/kg) of supercapacitors are compared with lithium-ion batteries and lead-acid batteries in Fig. 5.
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.
