The inferior energy density of supercapacitors compared to batteries has resulted in the supercapacitor’s role in limited energy storage applications . The short time constant of supercapacitors makes supercapacitors very effective in overcoming the negative effects of transients on battery performance.
Supercapacitors (SCs) deviate from the traditional design of electrostatic capacitors by employing aluminum current collectors and electrodes instead of dielectric materials. The fundamental mechanism behind the operation of SCs lies in the storage of energy through the distribution of ions near the surfaces of the two electrodes.
Supercapacitors, in particular, show promise as a means to balance the demand for power and the fluctuations in charging within solar energy systems. Supercapacitors have been introduced as replacements for battery energy storage in PV systems to overcome the limitations associated with batteries [79, , , , , ].
In reference [ 7 ], an energy self-equalization control strategy is proposed for the cascaded multilevel supercapacitor energy storage system. The system current can be directly used to balance the energy between modules, which can avoid the use of an external equalization circuit.
This provides further scope for developing high-performance supercapacitors that can augment the performance of hybrid energy storage systems that feature both battery and supercapacitors. Data is provided within the manuscript or supplementary information files. Nayak, S., & Joshi, D. (2015).
