The Battery Manufacturing Industry Winter School, held from March 24th to 27th, 2025, in Grenoble, France, successfully brought together 102 European researchers, trainers, industry professionals and students to explore battery production. As a co-organizer of the event, the BATTwin project played a pivotal role in advancing discussions on digitalization and cybersecurity in battery manufacturing.

Among the distinguished speakers, Prof. Marcello Colledani, BATTwin project coordinator, delivered an insightful presentation on digitally-enhanced zero-defect manufacturing, covering:  

(i) the challenges in battery cell manufacturing and opportunities for efficiency improvement,

(ii) the work performed within BATTwin for the development of process and system-level digital twins, with an introduction of models leveraged.

Overall, his session emphasized the role of system level digital twin technology for the production efficiency optimization, defects and scrap rates reduction in the gigafactories ramp-up phase – key KPIs in the push towards a more sustainable and competitive European battery industry.

Likewise, Prof. Nada Mimouni, cybersecurity expert within BATTwin, highlighted the growing importance of leveraging  ontologies and knowledge graphs to mitigate cyber-attacks in battery manufacturing facilities. As digitalization accelerates across the sector, her session addressed the critical need for robust security frameworks enabling advanced threat analysis and pattern identification for mitigation strategies development.

The Winter School featured an engaging mix of expert-led keynotes, hands-on training, and site visits to cutting-edge facilities, including the R&D Battery Platform CEA/Synchrotron ESRF and Verkor’s pilot cell production line. Participants, including PhD students and industry professionals, had the opportunity to gain practical and technical insights and build valuable collaborations at the intersection of academia and industry.

BATTwin’s contribution to the Winter School highlights its commitment to fostering innovation and strengthening Europe’s leadership in battery manufacturing. By integrating advanced digital solutions, the project continues to drive sustainable and efficient energy solutions for the future.
