Dürr and GROB unveil next-gen battery cell factory concept with 70% lower energy use
Press Release, 31 October 2025
Engineering leaders Dürr and GROB have joined forces to redefine lithium-ion battery manufacturing through their new concept factory—a breakthrough approach that reduces energy use by 70% and floor space by 50% while improving battery performance and quality. The two German engineering giants showcased their innovations at The Battery Show India 2025 in Greater Noida, highlighting a new era of efficient, sustainable, and localized battery production.
The concept factory integrates Dürr’s dry coating technology and GROB’s Z-folder cell assembly system, representing the next generation of battery cell production. Unlike conventional wet coating, Dürr’s X.Cellify DC system—developed in partnership with LiCAP Technologies—uses a dry-mixed active material pressed into a free-standing film. This eliminates the drying stage and solvent recovery process, significantly cutting energy consumption, costs, and environmental impact. The proof of concept confirms consistent high-quality output, and Dürr is now seeking industry partners for pilot projects.
Meanwhile, GROB’s new Z-folder with integrated notching enhances speed, stability, and reliability in cell assembly. Its precision-guided separator and efficient magazine buffer system achieve 95% machine availability, ensuring maximum uptime. Dürr also introduced a high-pressure electrolyte filling process capable of up to 30 bar pressure, enabling faster, more precise dosing without residual gas—reducing cycle times and enhancing cell performance.
Both companies are embedding end-to-end digitalization into the manufacturing chain using digital twins and MES/MOM software from iTAC, enabling complete process simulation, traceability, and quality control.
Since partnering in 2022, Dürr and GROB have aimed to position themselves as global system suppliers for lithium-ion battery production in Europe, North America, and India. By localizing technology and building partnerships, they aim to strengthen India’s Atmanirbhar Bharat initiative and accelerate the nation’s transition toward clean, self-reliant mobility.
