About the Consideration of the Inactive Materials and the Meshing Procedures in Computational Models of Lithium Ion Battery Electrodes

Abstract: Lithium‐ion batteries (LIBs) constitute a crucial technology in the ongoing energy transition. Still, the composite porous electrodes in LIBs remain complex systems which still need optimization to meet the requirements from the applications, e. g., high energy density for the automotive sector. To achieve well‐designed LIB electrodes, computational continuum modeling with three‐dimensional (3D) resolution constitutes a powerful tool to gain insights on the working principles of these electrodes. However, due … Show more

“…For computational strain reasons, the VGCF and PTFE were merged into one single phase known as the Carbon Binder Domain (CBD) in the modeling field. 17 The electrodes were stochastically generated using an in-house MATLAB code, which is provided as well as all the codes and the FEM template used to obtain the results presented in this article. This stochastic algorithm uses real NMC811 particles extracted from plasma focused ion beam (PFIB) data, 18 and generates CBD as fibers to mimic the morphology of VGCF and PTFE.…”
