Creating a Digital Bimodal Anode

The GeoDict tutorial on creating a bimodal anode provides practical insight into modeling battery electrodes using the GeoApp Bimodal Anode in GeoDict 2023. As the second part of a tutorial series on creating batteries from bimodal electrodes and subsequently performing degradation simulations, the video demonstrates step by step how to create a realistic anode structure in GeoDict.

The focus is on the various parameters and settings for electrode creation within the Battery GeoApps. The video demonstrates how to select graphite as the active material and precisely define the particle structure using parameters such as particle diameter, particle shape, and orientation tensors. Based on these settings, a bimodal anode with a porosity of approximately 10% and a slight deviation from the specified area capacity is then generated. The tutorial is intended in particular for GeoDict users who wish to model bimodal electrodes and use them as a basis for further battery simulations and degradation analyses.

• Creation of a bimodal anode: Step-by-step creation of an anode structure using the GeoApp Bimodal Anode in GeoDict 2023 as the basis for further battery and degradation simulations.
• Material selection and particle definition: Selection of graphite as the active anode material, definition of particle sizes, and setting of particle diameters for the bimodal particle distribution.
• Particle shape and orientation: Adjustment of the particles’ geometric properties, specification of the particle shape, and definition of orientation tensors for targeted control of the microstructure.
• Parameterization of the electrode structure: Setting the relevant parameters within the Battery GeoApps to model the desired composition and morphology of the anode.
• Generation and evaluation of the anode: Creation of the final anode structure with a porosity of approximately 10% and the smallest possible deviation from the specified area capacity.
