Description du projet
Une solution bio-inspirée améliore les performances des batteries lithium-ion
Des batteries rechargeables efficaces et durables sont indispensables pour alimenter les appareils électroniques portables et les véhicules électriques hybrides et pour stocker l'électricité provenant de sources renouvelables. Le projet HYNANOSTORE, financé par l’UE, entend développer une technologie de batterie polyvalente et respectueuse de l’environnement, basée sur l’utilisation de molécules organiques. HYNANOSTORE proposera une nouvelle architecture d’électrode qui augmentera la durabilité de la cathode, dépassant les limites des batteries lithium-ion. La clé de cette architecture est un échafaudage conducteur nanostructuré aux caractéristiques adaptées qui devrait permettre d’immobiliser les molécules redox-actives et d’étendre leur surface. Il facilitera également le transport des charges et l’interaction de l’électrode avec l’électrolyte. Le système d’ingénierie bio-inspiré proposé devrait améliorer la densité énergétique et la recyclabilité des batteries lithium-ion.
Objectif
Humanity will increasingly need safe, clean and always available energy. Thus, having good energy storage systems will be more and more important in the future. Efficient and sustainable rechargeable batteries are required to power portable electronic devices, new hybrid electric vehicles and to store electricity from renewable sources.
The mission of HYNANOSTORE is the development of new environment-friendly systems based on that organic molecules which are used in the chemistry of life for the storage of chemical energy and its transformation in electrical energy.
HYNANOSTORE re-thinks the concept of battery’s electrode based on lithium insertion and propose a novel architecture in which the redox properties of bio-molecules such as enzymatic co-factors can take up and release ions reversibly in order to overcome the problems (safety, sustainability and long-term ciclability) associated with the use of conventional Li ion batteries.
To achieve this, a nanostructured conductive scaffold with tailored characteristics will provide a framework to immobilize redox active molecules, extended surface area to maximize their loading, a pathway for the charge transport and a diffuse interface for the interaction with the electrolyte.
The new bio-inspired engineered system developed after the successful completion of HYNANOSTORE will offer benefits in terms of power and cyclability; an energy density of 500 W h kg-1 and the retention of at least 90% capacity after cycling 800 times are expected with the implementation of these systems.
The output of the project HYNANOSTORE will be the introduction of a new concept for lithium ion batteries towards cheap, green and versatile energy storage devices.
