Cabs Milestone I3 Report: Demonstration of Ability to Construct 3D Meshes of Electrodes Using Reconstructions from Micro-Tomography

Roberts, Scott A.; Ferraro, Mark E.

Mesoscale (100s of particles) electrochemical-thermal-mechanical models and simulations of NMC cathodes are a critical outcome of the CABS project. These simulations require mesostructure geometries and commensurate computational meshes on which to perform the simulations. While these geometries can be generated using a variety of methods, the highest-fidelity approach is to reconstruct the geometry directly from 3D experimental data/measurements. In this milestone report, we demonstrate our ability to create 3D computational meshes using the Conformal Decomposition Finite Element Method (CDFEM) on a selection of NMC cathodes that were imaged using X-Ray Computed Micro-Tomography (X-Ray CT, or simply XCT).
