Bioinspired, biphasic and bipolar flow batteries with boosters for sustainable large-scale energy storage

Descripción del proyecto

Una batería mejor para el almacenamiento de energía limpia a gran escala

La creciente preocupación por el cambio climático ha espoleado un cambio mundial hacia fuentes de energía más limpias. El reto consiste en garantizar que dichas fuentes puedan ir a la par del aumento de la demanda y en respaldar que se aborde adecuadamente la cuestión del almacenamiento de energía renovable. Por lo tanto, una de las prioridades fundamentales es encontrar tecnologías de almacenamiento rentables y sostenibles para esta enorme cantidad de energía. Para delinear el camino hacia las futuras tecnologías de baterías de tercera generación destinadas al almacenamiento de energía a gran escala, el proyecto Bi3BoostFlowBat, financiado con fondos europeos, desarrollará baterías rentables de bajo coste, alta solubilidad y con un potencial redox óptimo. El proyecto se propone lograrlo mediante la introducción de varias estrategias para encontrar los mejores compuestos que permitan obtener los resultados deseados.

Objetivo

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.
