Redox Electrolytes for Supercapacitors

Author(s): Jacob Koehler

Because of their short charging/discharging time, long cycle life, and good temperature characteristics, supercapacitors (SCs) have received a lot of attention. Electrolytes have been identified as a critical factor influencing the performance of SCs. They derive the majority of their energy density from their decomposition voltage and the majority of their power density from their ionic conductivity. Redox electrolytes have gained popularity in recent years due to their additional redox activity, which provides increased charge storage capacity in SCs. This article summarises the most recent advances in the study of redox electrolytes, focusing on their properties, mechanisms, and applications based on the various solvent types available. It also suggests potential solutions for increasing the energy density of SCs while maintaining their high power and long life.
