A 3D conversion technique is used to capture the NMC cathode geometrical shape under uniaxial compression at constant speed modeled by the simulated data. The data is segmented into its various material phases and voxelized to rebuild the microstructure in a format that can be used with the CNN architecture presented in the current work. In order to achieve it, the voxelization algorithm is applied to extract particle positions to create the voxel grid.
