Binoy K. Saikia, in Journal of Energy Storage, 2022 The capacitance mechanism of Electric Double Layer Capacitors is similar to that of dielectric capacitors. In conventional capacitors, energy is stored by the accumulation of charges on two parallel metal electrodes which separated by dielectric medium with a potential difference between them.
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 .
It has been reported that the capacitance of electric double layer capacitors is proportional to the ion concentration and 1/thickness of the double-layer and that the ion concentration is affected by the voltage between two electrodes and the polarization of the carbon electrodes.
Double layer capacitors are available with capacities of 10 F up to 5000 F, and specific energies around 4.5 Wh/kg (see Table 1). Specific outputs of 800–1200 W kg −1 are sufficient for most technical applications .
