Next-Generation Lithium-Ion Batteries
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.

Hundreds of synthetic graphite anodes were generated as digital material models during the project and used as training data for the Neural Network (NN).
Math2Market has validated a new method based on so-called Gaussian Random Fields (GRF) to generate a Digital Twin of an electrode microstructure.
A new method for the segmentation of 3D grayscale images was developed during the structur.e project and was implemented in the GeoDict software.
Math2Market, together with its partners in the structur.e project, has reached an important project milestone: Digital material models - so-called Digital Twins - of the microstructure of the anode and the cathode have been created and validated based on 3D CT-scans.
Within the structur.e project two new features for GeoDict 2021 (release in September 2020) have been developed.
