MeBattery project concludes: a step forward in sustainable battery technology
After three and a half years of dedicated research, the MeBattery project has come to a successful close. Through collaboration among experts in materials science, electrochemistry, and computational modelling, the consortium laid the foundation for innovative and sustainable battery concepts with potential applications in clean energy storage, e-mobility, and smart cities.
To close the project and reflect on its achievements, partners gathered for a final meeting at the International Research Center in Critical Raw Materials for Advanced Industrial Technologies (ICCRAM) in Burgos, Spain. Project coordinator Dr Edgar Ventosa from the University of Burgos highlighted the team’s breakthroughs:
“Through MeBattery, we have developed a new redox-flow battery concept based on thermodynamic principles, ensuring both high performance and environmental sustainability. We discovered and patented a novel organic compound that outperforms materials currently used in redox-flow batteries and developed innovative methods to enhance overall battery efficiency and performance. Together, these breakthroughs bring us closer to accessible, low-cost, and eco-friendly energy storage systems that support Europe’s clean energy transition.”
Key Results and Achievements
Over its duration, MeBattery laid the foundation for the next generation of battery technologies by:
- Developing a novel flow battery concept, opening new opportunities for flexible and scalable energy storage and creating new market opportunities
- Developing new viologen derivatives, leading to new viologen families and longer-lasting aqueous redox flow batteries
- Optimising the cell reactor design for mediated redox flow batteries, enabling a scalable, membrane-free system operating under optimal conditions
- Developing Prussian blue analogues, allowing energy storage production without dependence on critical raw materials
- Establishing a booster–mediator evaluation platform, introducing new methods to measure and analyse redox processes
- Implementing a solid capacity booster confinement strategy, confining the booster material as a single monolithic structure in the external reservoir of a redox-mediated flow battery
Taken together, these achievements demonstrate MeBattery’s ability to combine innovation with sustainability. The project’s results represent a meaningful step forward in next-generation battery research and in building a more resilient, sustainable energy future for Europe.
