Description du projet
Vers des supercondensateurs à haute densité à base de graphène
Les supercondensateurs sont des dispositifs de stockage d’énergie qui peuvent libérer de l’énergie à des taux élevés. Le projet ARMS, financé par l’UE, prévoit de mettre au point des supercondensateurs respectueux de l’environnement dont la densité énergétique est similaire à celle des batteries. Pour leur construction, les chercheurs intégreront différents matériaux tels que du carbone biosourcé riche en graphène et des fibres de carbone décorées de graphène. En utilisant le dépôt de couches atomiques, ils tenteront d’atteindre des densités d’énergie supérieures à 50 Wh/kg sans sacrifier la densité de puissance, le cycle de vie et le respect de l’environnement. Deux cas d’utilisation démontreront la viabilité du concept: un dispositif de capteur sans fil alimenté par un supercondensateur flexible imprimé, et un drone alimenté par des supercondensateurs structurels qui font également partie de la structure du drone.
Objectif
The overall objective of the ARMS project (Atomic layer-coated gRaphene electrode-Based Micro-flexible and Structural supercapacitors (ARMS) is to integrate comprehensive materials and processes, including graphene-rich bio-based carbon materials and graphene-decorated carbon fibers, and to develop scalable and cost-effective atomic layer deposition (ALD) manufacturing technology to fabricate totally eco-friendly supercapacitors with energy density reaching > 50 Wh/kg that is comparable to batteries without sacrificing the power density, cycle life or eco-friendliness, and open up opportunities to establish a new value chain for supercapacitor manufacturing with European SMEs as key players. The consortium will achieve this goal by a combination of factors, working in a coordinated fashion: process modification to enable production of high-graphene-content porous carbon for printed flexible energy storage, conformal graphene coating onto carbon fibres for structural supercapacitors, decoration of both types of electrodes with ultra-thin conformal ALD coating of MnO2 and Fe2O3 for increased stability and voltage window (to be scaled up to roll-to-roll by Beneq), and development of novel, environmentally-friendly electrolytes. The energy storage devices enabled by this work will be integrated into two use-case demonstrators to show the viability of the concept: a wireless sensor device powered a printed flexible supercapacitor, and a drone powered by structural supercapacitors which are simultaneously structural parts of the drone.
