| Abstract | High-power energy storage systems such as supercapacitors are one of the most promising energy devices, in which the capacitance results mainly because of the charge separation at the interface of electrode and–electrolyte. Recently, much attention has been paid toward solid-state and flexible supercapacitors for bendable, stretchable and wearable electronics. Simple and scalable fabrication processes of unique electrodes/electrolytes in highly flexible SCs is the need of the hour. Recent research shows that superior performance of supercapacitors is possible through the combination of advanced carbon/graphene-based electrodes and ion-conducting stable gel-polymer electrolytes. One of the main challenges of fabricating highly flexible and solid-state supercapacitors is developing and selecting highly functional and significant electrolytes. This is because of the overall performance of the constructed cell assembly is directly proportional to the stability of electrolyte. There are generally three types of electrolytes used for supercapacitor applications, including aqueous, organics, and room temperature ionic liquids. Among these, room temperature ionic liquid-based gel-polymer electrolytes are gaining commercial importance for solid-state/flexible supercapacitors due to their wide voltage potential, as they are resistant to the reduction and the oxidation reactions during operation. One of the major advantages for the room temperature ionic liquid-based gel electrolytes is the possibility of providing the cell voltage of around 4.5 V (sometimes up to 6 V), which makes them a unique choice for the construction of solid-state/flexible/stretchable supercapacitors . This chapter provides a comprehensive review of room temperature ionic liquid electrolytes for supercapacitors, their related performance comparisons, and the electrode–electrolytes interactions. Further, the electrochemical performance of solid-state supercapacitors in the presence of ionic liquid-based electrolytes is discussed. |
