Abstract (Englisch)	Reliability and innovations in current and upcoming battery technology as one core element of Europe’s green industrial transition are highly dependent on the understanding and systematic classification of the complex processes in advanced functional materials structured at the multiscale level. DigiCell provides a digitally integrated framework that improves reliability and quality in the manufacturing processes of high-performance Lithiumion batteries (LIB) and beyond Lithium battery technologies through unified and adaptive models capturing the structure-property relationships in these complex energy materials. It is based on a toolset of innovative and state-of-the-art characterisation methods for multiscale materials, interoperable tests, and analytical models supported by and linked through machine learning. With this, the production costs, materials waste, and the CO2 footprint in production lines will be reduced, while in parallel the battery electrochemical performance at the single cell level will be increased. The new measurement tools and multi-scale modelling algorithms lead to a higher characterisation speed (factor of 5) and an improved accuracy in cell tests by an order of magnitude, as will be demonstrated on the lab bench and in pilot lines. DigiCell develops a new holistic approach for opensource algorithms and data standardization strategies; new quality assessments for a healthy, safe, and circular economy. The project readily interfaces and interacts tightly with EMMC.
