Abstract

The reduced graphene oxides (RGOs) functionalized by pyridinium-based ionic liquids (ILs) with SCN anions revealed 6-fold higher capacitance compared to that of RGOs due to the redox behavior of ILs as well as good rate capability and cycle stability despite the appearance of pseudo-capacitance.
