Projektbeschreibung
Sind Graphenderivate der Schlüssel zu besseren Superkondensatoren?
Kondensatoren und Batterien speichern Energie und geben sie bei Bedarf wieder ab. Ohne sie ist kein Übergang von den fossilen Brennstoffen zu den nicht ständig verfügbaren erneuerbaren Energien denkbar. Während der weltweite Energiebedarf weiter ansteigt, wird es uns mit diesen technischen Mitteln gelingen, die sich explosionsartig ausbreitenden tragbaren Geräte und Sensoren in den Randbereichen des Internets mit Strom zu versorgen. Superkondensatoren sind Batterien auf vielerlei Art überlegen, aber obwohl sie mehr Energie als konventionelle Kondensatoren speichern, verlieren sie das Rennen gegen die Batterien dennoch mit großem Abstand. Das EU-finanzierte Projekt UP2DCHEM wird die Fertigung eines neuartigen Graphenderivats für Superkondensatorelektroden hochskalieren. Mit diesem Schritt könnte sich alles ändern und für diese kleineren und robusteren Speichergeräte eine führende Position in greifbare Nähe rücken.
Ziel
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.
