    The digital transformation in research opens up numerous opportunities to develop innovative, data-based offerings and new, digital business models. For the Fraunhofer-Gesellschaft, this transformation is both a challenge and an opportunity, as digitalization requires not only the development of a suitable infrastructure but also a change in work culture towards standardized data management. A consistent digitalization of research and development activities will be indispensable in the future: on the one hand, in order to meet the requirements of national and international funding institutions in dealing with data, and on the other hand, in order to be able to compete internationally. | Duration: 02/2024 - 01/2027

    Examination of a pouch cell using SAM (Scanning Acoustic Microscopy). The setup will be further developed and optimized in the project.

    Inhomogeneities in battery cells have a negative impact on service life and jeopardize safe operation. Currently, there is a lack of suitable detection options in battery cell production to identify such defects reliably, quickly and cost-effectively. As part of the »SAMBA« research project, an ultrasound-based non-destructive testing method is being developed to inspect battery pouch cells for quality assurance purposes. Scanning Acoustic Microscopy (SAM) is used to generate image data that is subsequently analyzed by an automated AI-based evaluation routine. The goal of the project is to build a demonstrator for the random rapid analysis of pouch cells and test it in a real-world operational environment. | Duration: 06/2023 - 05/2026
