The CIRCUBATT project aims to redefine the European battery sector by setting new benchmarks through the integration of artificial intelligence, data analytics, and sustainable practices. By tackling critical bottlenecks and employing cutting-edge technologies, CIRCUBATT seeks to boost the competitiveness of the European industry while aligning with the EU’s environmental and economic objectives. Its holistic approach promises a more efficient, reliable, and sustainable battery value chain, prepared to address Europe's future energy demands and the global challenge of climate change. The project combines advanced material sciences, innovative business models, and leading digital technologies to deploy a range of solutions tested across various real-world scenarios. These solutions will span the entire battery lifecycle—from design and manufacturing to end-of-life recycling—showcasing adaptability, efficiency, and sustainability in practical applications. This initiative aims to reduce Europe’s reliance on critical raw materials, diminish environmental impacts, and strengthen the continent’s position in the global battery market. CIRCUBATT will explore innovative business models, such as Battery-as-a-Service (BaaS) and develop cross-industry tools like battery sustainability analysis and artificial intelligence-driven data analytics. Additionally, it will advance the design of battery cells and packs that support effective aging analysis and facilitate dismantling for second-life use or recycling. Pilot studies within the project will validate the feasibility of these innovations. Ultimately, the project will deliver new products, business models, and tools poised to make significant contributions to the circularity, resilience, and sustainability of the European battery value chain.
