The preliminary data showed that chemistry of fluorographene, which has been developed in the framework of ERC Consolidator project 2DCHEM, can lead to efficient synthesis of graphene derivatives having properties suitable for supercapacitor electrode materials. Subsequently, project UP2DCHEM aimed to deliver the upscaling of an industrially-relevant one-chemical-step novel manufacturing process, based on chemistry of fluorographene, resulting in a supercapacitor electrode material. The as prepared novel covalent graphene derivative enables a significant boost in the gravimetric/volumetric energy density, without sacrificing the rate performance, i.e. power. A significant business opportunity has been created through implementing novel and cost-effective materials and processes.
