CustomCells, a German battery cell developer, has joined a practical research initiative under the state of Baden-Württemberg’s “Innovation and Future Agenda.”
The company will contribute to a collaborative effort aimed at advancing large-format round cell technology — a format gaining significance in electric vehicle (EV) and other high-performance applications.
Scientific partners include the Center for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW), the Fraunhofer Institute for Manufacturing Engineering and Automation (Fraunhofer IPA), and the Karlsruhe Institute of Technology (KIT). The state has committed €8 million in funding to support the initiative.
CustomCells will establish its round cell pilot line at its facility in Tübingen. The project will focus on designing and producing 46 mm large-format cylindrical cells, known for their robust construction, heat management, and high energy density.
These characteristics make round cells particularly relevant for demanding use cases in premium EVs, as well as applications in motorsport, aerospace, defense, and industrial machinery.
The research will also explore digitalization and automation strategies to support efficient scaling from pilot to industrial-scale production.
With its Tübingen pilot plant, CustomCells aims to strengthen local battery development capabilities and contribute to European efforts to reduce reliance on imported battery technologies. The company’s participation supports the broader strategy of developing competitive EV and battery ecosystems within Germany and the EU.
The initiative is expected to build critical expertise in battery innovation and production across Baden-Württemberg, supporting industrial competitiveness in next-generation energy storage solutions.
