We present a three-dimensional physics-based modeling workflow to study the impact of wet manufacturing process parameters on the properties of Solid-State Battery (SSBs) tape casted electrodes. This computational workflow was initially developed to study Lithium Ion Battery electrodes within our ARTISTIC project and it is adapted here to SSB cathode electrodes based on NMC622 active material. SSB electrode manufacturing remains almost unstudied in terms of computational modeling, with just a handful of simulation studies in the literature. Our workflow simulates the slurry constituted of active material, carbon additive, binder, solid electrolyte and solvent, its drying, and the calendering of the resulting electrodes. We focus our attention on the impact of the compression degree on the electrode microstructure. We believe that this first wet manufacturing process model of SSB cathodes paves the way towards systematic modeling approaches able to provide practical guidelines on how to tune interfaces between materials in electrodes for proper SSB performance and durability.
