Description du projet
Les dérivés du graphène pourraient être la clé de supercondensateurs de classe supérieure
Les condensateurs et les batteries stockent l’énergie et la libèrent en fonction des besoins, favorisant ainsi notre transition pour passer des combustibles fossiles aux énergies renouvelables intermittentes. Dans la mesure où la demande mondiale d’énergie continue d’augmenter, ces dispositifs devraient nous aider à alimenter la croissance exponentielle attendue des appareils portables et des capteurs sur les réseaux périphériques de l’Internet. Bien que les supercondensateurs soient supérieurs aux batteries à bien des égards, et bien qu’ils stockent plus d’énergie que les condensateurs classiques, ils perdent encore largement la course face aux batteries. Le projet UP2DCHEM, financé par l’UE, permettra de fabriquer à grande échelle un nouveau dérivé du graphène pour les électrodes des supercondensateurs, ce qui pourrait changer la donne et placer ces dispositifs de stockage plus petits et plus robustes en position de leader sur les marchés.
Objectif
The world population is significantly increasing and its reliance on energy-based devices is higher than ever before. This leads to a continuous rise in global energy consumption. Considering that fossil fuel resources are strictly limited and have a detrimental effect on our environment, it is understandable that research focused on sustainable energy resources, coupled with suitable energy storage technologies, attracts an intense interest. In addition, the ever-growing number of electric bikes and cars, portable devices and sensors requires quickly rechargeable, long-life cycle and safe power supply. Supercapacitors belong to the group of energy storage devices that display significant advantages over batteries or fuel cells, such as high-power density, extralong cycle life, and a small size. They can store more energy than conventional capacitors; however, the energy they can store is approximately one order of magnitude lower than that of batteries.
The preliminary data show that chemistry of fluorographene, which has been developed in the framework of ERC project 2DCHEM, can lead to efficient synthesis of graphene derivatives having properties suitable for supercapacitor electrode materials.
This project aims 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 will arise through implementing novel and cost-effective materials and processes.
