Unleashing the Power: Superior Properties of Fluorographene-Derived Materials for Energy Storage Applications

„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 (trans2Dchem.com) 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.
