The advancing climate change requires a shift from conventional energy sources to renewable ones, which is accompanied by the indispensability of an efficient and sustainable storage of electrical energy.  Lithium-Ion batteries have proven to be a key technology for a wide range of applications due to their variety of use. The production of Lithium-Ion battery cells comprises an enormous complexity, as it consists of several interlinked process steps, each with different quality requirements for the (intermediate) products and the process itself.
In a modern and digital factory data is collected during production and of the (intermediate) products aiming at process optimization to ensure a consistent quality. The digital twin enables the aggregation of data, information, models and simulations. Digital twins are becoming increasingly relevant for various areas of production. In particular, the complex battery cell production benefits from digital twins. Various data-based services are enabled by digital twins that are used to track, optimize and control products and processes, thus increasing sustainability.

Antje Fitzner studied physics and got her doctorate in geophysics. After several years as team leader Data Science at a Münster-based company, she is now a research associate in the field of digitalization of the battery cell production at the Fraunhofer Research Institution for Battery Cell Production FFB in Münster since 2021. Her core topics include the conceptual design and implementation of AI/ML applications, the Digital Twin and data-based production optimization.
