From: Graphene quantum dots as the electrolyte for solid state supercapacitors
(a, b) Galvanostatic charge-discharge curves and (c–f) CV curves of the assembled supercapacitors using GNSs as the exemplified electrode material and GQD or NGQD solutions, or GQD or NGQD solid-state films as the electrolytes. The as-used electrolytes were marked in each of the figures.
