The event brought together international experts and 140 participants, with 45 presentations and over 50 posters focused on battery characterisation. High-level scientific results were presented, which are crucial for the THOR project, relying on a wide range of experimental techniques essential for understanding the degradation mechanisms that affect battery performance, lifespan, and safety.
Some of these, such as X-ray diffraction, absorption, tomography, microscopy, Raman spectroscopy, electrochemistry, etc, have been largely experimented. With these, test limitations were also discussed, including side effects related to sample preparation, beam damage during data acquisition, and the lack of sample representativity.
These experimental aspects are particularly relevant for THOR, as they will impact the parameterization of physics-based models and may explain some discrepancies between simulations and real models.
Addressing such experimental biases has been essential for the project’s success.
