On October 9, 2025, the BATTwin project was proudly presented by Politecnico di Milano Assistant Professor Ozan Emre Demir during the SP2025  FULL-MAP Clustering Event, held online.

Organised by the FULL-MAP project in collaboration with the BATT4EU and BATTERY 2030+ initiatives, this workshop aimed to strengthen cross-project collaboration within Europe’s battery research ecosystem. The event featured 11 European project presentations and roundtable discussions designed to identify synergies, avoid duplication, and define joint actions in key areas such as data standards, advanced characterisation, and the circular economy. By fostering dialogue across the European battery community, the session sought to build a cohesive network and co-develop future cooperations and impact.

The event was structured around three thematic sessions exploring synergies across the battery value chain:

• Session 1 Platforms, Interfaces & Understanding Fundamentals
• Session 2 Safety, Smart Functionalities & Advanced Chemistries
• Session 3 Manufacturing, Digitalisation & Circularity

In his talk Ozan introduced BATTwin’s innovative digital twin platform, designed to accelerate zero-defect battery manufacturing and support the efficient ramp-up of European gigafactories. The presentation highlighted how the platform integrates real-time process data, modelling, and advanced quality control to detect deviations early-on, reduce material waste, and optimize overall throughput in cell production at gigafactory scale.

Among the research and industrial questions the project aims to address are the following:

• What changes introduced at process level will impact the system’s overall performance?
• How can we interconnect input & output parameters across the process-chain to formalize defect deviation and aggregation patterns?
• What is the impact of the process-level developments on system-level performance?
• How can diverse tools be integrated into a single, coherent platform while managing distributed, heterogeneous data and unique workflows?

By answering these questions, BATTwin advances the European battery sector toward fully digitalised, high-yield, and sustainable manufacturing, ultimately contributing directly to the Battery 2030+ vision, strengthening Europe’s industrial competitiveness, fostering data-driven innovation, and enabling a sustainable battery value chain.
