Descrizione del progetto
I derivati del grafene potrebbero essere la chiave per supercondensatori superiori
I condensatori e le batterie immagazzinano energia e la rilasciano a seconda delle necessità, supportando la nostra transizione dai combustibili fossili all’energia rinnovabile intermittente. Poiché il fabbisogno energetico globale continua ad aumentare, questi dispositivi ci aiuteranno ad alimentare l’esplosione di dispositivi e sensori portatili ai margini di Internet. I supercondensatori sono superiori alle batterie in vari modi ma, sebbene immagazzinino più energia rispetto ai condensatori convenzionali, perdono la gara con ampio margine quando si tratta di batterie. Il progetto UP2DCHEM, finanziato dall’UE, incrementerà la produzione di un nuovo derivato del grafene destinato agli elettrodi dei supercondensatori, in grado di superare il problema grazie a questi dispositivi di stoccaggio più piccoli e robusti.
Obiettivo
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.
