Descrizione del progetto
Una batteria migliore per uno stoccaggio dell’energia pulita su larga scala
Date le crescenti preoccupazioni relative cambiamenti climatici, si assiste a una transizione mondiale verso fonti energetiche più pulite. La sfida consiste nel garantire che queste fonti riescano a stare al passo con la crescente domanda e nell’assicurare che il problema dello stoccaggio delle energie rinnovabili sia adeguatamente affrontato. Pertanto, trovare soluzioni di stoccaggio economiche e sostenibili per questa enorme quantità di energia è una priorità di primaria importanza. Per tracciare la strada verso le future tecnologie di batterie di terza generazione per uno stoccaggio dell’energia su larga scala, il progetto Bi3BoostFlowBat, finanziato dall’UE, svilupperà batterie economiche caratterizzate da costi bassi, un eccellente potenziale di ossidoriduzione e un’elevata solubilità. Il progetto intende ottenere ciò con l’introduzione di diverse strategie, con l’obiettivo di trovare i composti migliori che condurranno ai risultati auspicati.
Obiettivo
To satisfy our growing energy demand while reducing reliance on fossil fuels, a switch to renewable energy sources is vital. The intermittent nature of the latter means innovations in energy storage technology is a key grand challenge. Cost and sustainability issues currently limit the widespread use of electrochemical energy storage technologies, such as lithium ion and redox flow batteries. As the scale for energy storage is simply enormous, the only option is to look for abundant materials. However, compounds that fulfil the extensive requirements entailed at low cost has yet to be reported. While it is possible that the holy grail of energy storage will be found, for example by advanced computational tools and machine learning to design “perfect” abundant molecules, a more flexible, innovative solution to sustainable and cost-effective large-scale energy storage is required. Bi3BoostFlowBat will develop game changing strategies to widen the choice of compounds utilizable for batteries to simultaneously satisfy the requirements for low cost, optimal redox potentials, high solubility and stability in all conditions. The aim of this project is to develop cost-efficient batteries by using solid boosters and by eliminating cross over. Two approaches will be pursued for cross-over elimination 1) bio-inspired polymer batteries, where cross-over of solubilized polymers is prevented by size-exclusion membranes and 2) biphasic emulsion flow batteries, where redox species are transferred to oil phase droplets upon charge. Third research direction focuses on systems to maintain a pH gradient, to allow operation of differential pH systems to improve the cell voltages. Limits of different approaches will be explored by taking an electrochemical engineering approach to model the performance of different systems and by validating the models experimentally. This work will chart the route towards the future third generation battery technologies for the large-scale energy storage.
