Description du projet
Une nouvelle solution pour l’énergie durable grâce aux textiles intelligents
Dans le monde actuel axé sur l’énergie, il est essentiel de chercher des solutions énergétiques efficaces et durables. Les approches traditionnelles ne permettent pas d’exploiter et de stocker l’énergie tout en restant respectueuses de l’environnement. Dans cette optique, le projet GRAPHERGIA, financé par l’UE, entend révolutionner la récupération et le stockage de l’énergie grâce à de nouvelles méthodes de fabrication d’électrodes sèches. La synthèse, la fonctionnalisation et l’intégration de matériaux à base de graphène dans des électrodes, assistées par laser, ouvriront la voie à la production de dispositifs de stockage d’énergie neutres sur le plan climatique. L’objectif global consiste à mettre au point des textiles électroniques durables et autorechargeables qui génèrent de l’énergie à partir de la récupération d’énergie biomécanique et d’électrodes de batteries Li-ion à base de matières premières peu coûteuses. L’utilisation de textiles autonomes sur le plan énergétique favorisera la recharge sans batterie et la connectivité de l’internet des objets.
Objectif
GRAPHERGIA aims is to develop a new science-based, holistic approach, implementing new advances to achieve one-step, laser-assisted synthesis, processing, functionalization and simultaneous integration of graphene-based materials and graphene nanohybrids, directly into relevant energy harvesting/storage devices. This will lead to a scalable, cost-effective and climate-neutral production of (i) e-textiles with the specific functions of wearable power supplying and self-powered structural sensors and (ii) next generation electrodes for Li-ion batteries. Based on current TRL 3-4 activities, the consortium explores novel ideas for 2D materials engineering and integration at TRL 5 or higher, establishing versatile pilot-scale-based approaches for these two types of applications. Configurations of TENG-based e-textiles will be prepared to fabricate flexible architectures, designed to sustainably convert energy from the environment to electricity. Laser-scribed solid-state micro-flexible supercapacitors, will be coupled to TENGs, via innovative power management circuits, acting as energy reservoirs to provide on-demand batteryless charging to wearable devices and sensors. All-in-one, self-charging power textiles with integrated electronic systems will provide a human-body-centric technology and interface of the user to the IoT by wireless transmission of sensors’ signals. In parallel, GRAPHERGIA defines a credible “dry electrode” approach to fabricate next generation electrodes for Li-ion batteries aspiring to reach the technical/economic targets of the 2030 European SET-plan. The proposed methodology will be implemented by blending recently devised IPR-protected technologies of consortium partners. To achieve these targets, a combined 2D materials and process-oriented approaches will be adopted, based on low-cost raw materials and inherently scalable fabrication approaches to ensure a cost-effective and climate-neutral production of energy harvesting and storage devices.
