Projektbeschreibung
Eine bessere Batterie für eine umfangreiche, saubere Energiespeicherung
Da die Sorge über den Klimawandel stetig wächst, ist weltweit eine zunehmende Hinwendung zu sauberen Energiequellen zu beobachten. Dabei gibt es mehrere Herausforderungen. So muss einerseits garantiert werden, dass diese Quellen dem steigenden Bedarf nachkommen können und andererseits, dass die Frage der Speicherung von erneuerbarer Energie hinreichend geklärt wird. Die Suche nach kostengünstigen und nachhaltigen Speichersystemen für diese enorme Menge an Energie steht daher an oberster Stelle. Um die Route zur Batterietechnik der dritten Generation für eine umfangreiche Energiespeicherung abzustecken, wird das EU-finanzierte Projekt Bi3BoostFlowBat kostengünstige Batterien entwickeln, die mit geringen Kosten einhergehen, ein optimales Redoxpotential bieten und eine gute Löslichkeit aufweisen. Dazu möchte das Projektteam verschiedene Strategien einführen, um die besten Verbindungen zu finden, die zu den gewünschten Ergebnissen führen.
Ziel
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.
