Adding redox activity into ionic liquids (ILs) extends their practical roles beyond an inert ionic conductor or electrolyte for applications in electrochemical energy storage. Especially for supercapatteries, redox ILs are desirable because they can contribute to increasing the charge storage capacity by merging the capacitive and Nernstian storage mechanisms without compromising their intrinsic wide potential windows. Several prospects of redox ILs are identified and discussed for optimising performance in supercapatteries.
