Why are supercapacitors used in limited energy storage applications?

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.

How do Supercapacitors work?

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.
