The European Commission has announced the call under the Batt4EU Partnership to integrate advanced materials, cell design, and manufacturing development and accelerate the production of high-performance batteries aimed specifically at mobility applications.
The focus areas include integrating advanced materials, cell design, and manufacturing development for high-performance batteries aimed at mobility within the Batt4EU Partnership.
This initiative under the Horizon Europe Work Programme seeks to support the transition of European battery cell manufacturers from incumbent generation 3 liquid electrolyte lithium-ion batteries to high-performance solid-state lithium-ion batteries. The projects funded will contribute to increased diversity of chemistries and cell designs that are oriented towards specific applications, enabling European Original Equipment Manufacturers (OEMs) to remain competitive. The development targets scaled production for premium products in medium-term applications such as aviation, with longer-term goals aiming at large-scale production.
The scope covers quasi-solid and all-solid-state lithium-ion battery technologies containing up to 5% liquid electrolyte weight. The technologies may include silicon-carbon composite anodes or lithium metal anodes. Projects are expected to focus on optimizing and testing critical manufacturing processes within existing production lines and not overhaul entire production systems. These processes should improve production yield, quality, cost-efficiency, and sustainability aspects such as energy consumption.
Activities involve adaptations of existing machinery, development and implementation of technological innovations supporting improved manufacturing processes, feasibility and impact validation through pilot testing, and metrics evaluation such as energy consumption reduction and product consistency enhancement. Projects will tailor battery cell designs to maximize the benefits of improved manufacturing processes by developing or integrating advanced materials.
Digitalization, data integration, analytics, and process control are central, requiring the implementation of advanced control systems and new process simulations. Development, exploitation, and harmonization of advanced diagnostic methods will enhance data depth on battery degradation and safety. Artificial intelligence and generative AI are employed to improve experimental design and testing efficiency, accelerating achievement of significant outcomes.
The expected results include shortened development cycles for battery cells and systems, improved battery reliability and safety through understanding aging and safety-relevant mechanisms, and reliable verification methods combining physical and virtual testing. The projects aim to support a transition to solid-state battery technologies that significantly improve the competitiveness and sustainability of European mobility.
Successful outcomes will contribute to meeting European Green Deal goals, bolstering the European battery value chain’s scientific, technological, economic, and societal impact with consideration given to scalability, commercialization, and deployment strategies.
