摘要：

We show, for the first time, a redox-active electrolyte in combination with a polyaniline-coated curved graphene activematerial to achieve significant enhancement in the capacitance (36-92% increase) compared to supercapacitors that lack the redox-active contribution from the electrolyte. The supercapacitors based on the redox-active electrolyte also exhibit excellent rate capability and very long cycling performance (>50 000 cycles).
