Electrodes are responsible for various energy storage mechanisms in supercapacitors, while electrolytes are crucial for defining energy density, power density, cyclic stability, and efficiency of devices. Various electrolytes, from aqueous to ionic liquid, have been studied and implemented as potential electrolytes for supercapacitors.
Classification of supercapacitors has been discussed. Supercapacitors are considered comparatively new generation of electrochemical energy storage devices where their operating principle and charge storage mechanism is more closely associated with those of rechargeable batteries than electrostatic capacitors.
Electrolytes are the key for supercapacitive devices to have a high power and energy density, long cycling life, and safety. Ionic mobility and conductivity are the important factors to evaluate the performance of electrolytes.
Charge storage in supercapacitor electrodes makes use of the electrostatic attraction between the ions of an electrolyte and the charges present at the electrode surface, which allows the formation of oppositely charged layers at the electrolyte/electrode interface.
Several energy storage technologies are available, including batteries, capacitors, and supercapacitors . However, supercapacitors are quickly gaining interest owing to their high cycle stability and power density with less environmental effect.
This relationship elucidates the rationale behind researchers' focus on developing high-surface-area electrode materials and optimizing electrolyte properties to maximize capacitance and, consequently, the energy storage capability of supercapacitors.
