New battery technologies that are affordable and sustainable over the entire life cycle are crucial to achieve the goals of the European Green Deal. The EU project TwinVECTOR was successfully concluded after a three-year period, having met its objectives to significantly enhance the research and innovation capacity of the centre of excellence at the Tomas Bata University (TBU) in Zlín, Czech Republic. With the support of the consortium partners, the project achieved a technical and institutional expansion of the TBU centre, enabling multidisciplinary national and international project teams to effectively network, create synergies, and collaboratively advance battery energy storage technologies. The project, which was supported by the EU with EUR 1.3 million, successfully fostered cooperation among five partners from the Czech Republic, Germany, Finland, and Austria, and established a strong, sustainable foundation for future research in this critical area.
