structur.e - Next-Generation Lithium-Ion Batteries

Your Browser doesn't support html5.

With structur.e, Math2Market GmbH and Volkswagen are pursuing the development of next generation lithium-ion batteries for electric mobility. The final goal is to significantly reduce the charging time for electric vehicles and to enable a longer range.

Get ready to explore the new digital possibilities to develop advanced battery materials!

The approaches in material development and battery research, enabled by the GeoDict software in this project, are also available for other applications! The GeoDict software allows to digitally create realistic material models of the battery materials microstructure using Artificial Intelligence. These digital models are used to simulate a variety of microstructuring processes, such as the use of a laser to create three-dimensional structures. The influence of these methods on the transport processes in the battery is then studied and quantified digitally on the microscale to find new design principles for next-generation materials.

    First Project Milestone

    Within the structur.e project two new features for GeoDict 2021 (release in September 2020) have been developed:

    • The BinderFind tool in the GrainFind module of GeoDict ensures the identification of the carbon black-binder domain (CBD) in electrodes. Specially trained Artificial Neural Networks allow the creation of even more realistic material models (Statistical Digital Twins).
    • Anisotropic diffusivity in the DiffuDict module of GeoDict takes into account the anisotropy of active materials regarding ion diffusion in simulations, which is particularly important for anodic graphite.

    Start of the structur.e project

    The structure.e project has officially started today. We are looking forward to the work with our partners and to three and a half exciting project years.
