Description du projet
Des batteries au lithium qui peuvent s’auto «guérir»
Le projet HIDDEN, financé par l’UE, prévoit de mettre au point des processus d’auto-guérison qui pourraient prolonger la durée de vie des batteries lithium-métal de 50 % et permettre ainsi la production de batteries durables de nouvelle génération avec une densité d’énergie pendant leur durée de vie 50 % plus élevée que les batteries lithium-ion actuelles. L’accent sera mis principalement sur la production de nouvelles technologies d’électrolytes à cristaux liquides thermotropes autocicatrisants et de séparateurs piézoélectriques. La modélisation multi-échelles de la conception d’électrolytes permettra aux chercheurs d’obtenir des informations précieuses sur la croissance des dendrites qui se produit dans les batteries lithium-métal. Le projet rassemble des partenaires universitaires et industriels ayant une expertise dans la chimie et la physique des batteries, la modélisation des matériaux, l’impression et le revêtement, et l’assemblage de cellules de batteries industrielles.
Objectif
The HIDDEN project develops self-healing processes to enhance the lifetime and to increase the energy density of Li-metal batteries 50 % above the current level achievable with current Li-ion batteries. The HIDDEN consortium develops materials and their processes to functional battery layers as scalable, industry compatible, manufacturing technologies enabling sustainable energy storage technology with longer battery lifetime and higher energy storage capacity for more efficient utilization of sustainable, carbon free energy production technologies.
HIDDEN will develop novel self-healing thermotropic liquid crystalline electrolytes and piezoelectric separator technologies, investigate both technologies with protective additives, and apply multiscale modelling means for electrolyte design and analysis algorithm to monitor the dendrite growth. Technologies will be upscaled from laboratory to industrial manufacturing processes, tested and finally demonstrated by assembling battery cells with battery layers and the temperature control system.
The project brings together a strong interdisciplinary consortium of seven partners, industry and research balanced, with state-of-the-art background in battery chemistry and physics, materials modelling and analysis, upscaling of novel technologies by printing and coating, as well as in industrial assembling of battery cells. This is complemented by external advisory board with representation of key industry end-users.
