This thesis presents the results I obtained in the context of the European Research Council-funded ARTISTIC project, where my work was centered on three-dimensional simulations of lithium-ion battery electrode manufacturing. These simulations allow linking manufacturing parameters to electrode microstructure, considering both the active material and the carbon-binder domain phases. In particular, three steps of the electrode manufacturing line were modeled and studied: the slurry phase, its drying, and electrode calendering. All the models developed are presented in detail, focusing on both their advantages and disadvantages, and the results obtained using them are illustrated. These models offer the possibility of studying a vast parameter...
