Deeper understanding of the complex phenomena underlying the interface between graphene-based electrodes and the electrolyte is crucial to increasing capacity in next-generation energy storage devices such as supercapacitors.
Graphene, a single layer of carbon atoms, is an attractive electrode material for supercapacitors because of its high surface area and high electronic conductivity. Similarly, ionic liquids are outstanding candidates owing to their high electrochemical stability. However, how the ionic liquid electrolytes interact with carbon material is still not well understood.
