Efficient and sustainable rechargeable batteries are crucial for powering portable electronic devices and hybrid electric vehicles and for storing electricity from renewable sources. The EU-funded HYNANOSTORE project targets the development of versatile, environment-friendly battery technology based on the use of organic molecules. HYNANOSTORE will propose a novel electrode architecture that renders the cathode sustainable, thereby surpassing the limits of lithium-ion batteries. The key is a nanostructured conductive scaffold with tailored characteristics that should help immobilise the redox-active molecules and extend their surface area. It will also facilitate charge transport and electrode interaction with the electrolyte. The proposed bio-inspired engineered system is expected to improve energy density and recyclability of lithium-ion batteries.
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.
