„GN3 (prepared by the reaction of fluorographene with sodium azide) stands out as a nitrogen-doped graphene with exceptionally high levels of nitrogen (∼16 %) and containing diamond-like bonds. Compared with graphite, it has a higher density of 2.8 g/mL. This unique material exhibits unprecedented capacitive behavior. When utilized as active material in a symmetric capacitor, paired with an ionic liquid electrolyte (1-ethyl-3-methylimidazolium tetrafluoroborate, EMIM-BF4, and 1,1,2,2-tetrafluoroethyl-2,2,3,3-tetrafluoropropyl ether (TTE) in a 9 : 1 ratio), it displays remarkable volumetric energy density (200 Wh/L) and power density (52 kW/L) while maintaining excellent cycling stability (Figure 5). Since such values are record among the high-performance supercapacitor materials (Figure 6), commercialization of the nitrogen-doped graphene (labeled as SC-GN3) is under development with the support of the EIC Transition project ( funded by the European Union. The qualification of the initial prototypes, featuring both wound (cylindrical) and pouch geometries, is scheduled for 2024.“ … read more about graphene derivatives for energy storage in our article published in Power Electronic Devices and Components journal.
