Abstract
Improving energy materials on the microscale is increasingly unavoidable to comply with the competing demands of the market for performance, high power density, fast charging, durability, and safety.
Simulations with GeoDict are an efficient approach to tackle these challenges. A typical workflow using GeoDict looks as follows:
- A scan of a physical reference material is segmented and imported into GeoDict.
- On the resulting 3D model, several geometrical analyses are performed.
- The structure is rebuilt in GeoDict. This so-called statistical digital twin mimics the macroscopic behavior of the material.
- Starting from this twin, microstructural design is possible to match the desired properties on a larger scale.
GeoDict 2023 includes new features to improve the effectiveness of this energy materials design process workflow. These features include macroscopic battery charging simulations, binder identification in graphite anodes, simulations of the mechanical behavior of electrodes during charging, and concentration-dependence of electrochemical parameters. For fuel cells, the software includes easier usage of saturation simulations and a GeoApp to generate Solid-Oxide Fuel Cells structures.
Other advances in the GeoDict 2023 release involve improved AI-based image segmentation and a convenient button to run simulations directly in the cloud. The ability to optimize digital twins to match specified properties and up to 255 material IDs enable more complex simulations and creative approaches to material design. Insight into the planned features of upcoming releases are given in the talk.
