To generate the data for training and testing we use the physics-based computational electrode manufacturing simulation workflow previously reported by us. This workflow consists of the sequential linking of the CGPD approach, to simulate the slurry and its drying, and DEM, simulating the calendering of the resulting electrode. In the current work, we specifically focus on the calendering step for one electrode formulation: 96 % NMC111 -2 % C65 -2 % PVdF (96 % AM and 4 % carbon-binder domain -CBD-in the simulation). Four synthetic electrodes were prepared. For each electrode, seven CD values were simulated: 20 %, 25 %, 30 %, 35 %, 40 %, 45 % and 50 %, resulting in a total of 28 calendering simulations. Each simulation consists of a series of timeframes that capture the microstructure evolution over time during the calendering process. For the current work, we keep the compression rate constant, therefore the number of timeframes (steps) that we have per CD value is 14, 18, 21, 24, 28, 31 and 35, corresponding to 20 %, 25 %, 30 %, 35 %, 40 %, 45 % and 50 % CD respectively. Each timeframe corresponds to 75 microseconds of simulation time.
