In this talk I present the recent progresses we achieved within the ERC Project ARTISTIC [1]. This pionnering project aims at developing a comprehensive, flexible and multiscale computational platform simulating the fabrication process of battery cells [2,3]. The project is supported on three pillars: 1) computational white box simulation tools, 2) experimental screening, and 3) black box machine learning techniques. I discuss in particular our recent results obtained by employing Coarse Grained Molecular Dynamics to simulate slurries, electrode self-organization upon solvent evaporation and the calendering stage. The resulting predicted electrode mesostructures are incorporated into a performance simulator resolving in three dimensions the interplays between electrochemistry, transport and mechanical processes in an operating battery cell. I discuss in particular how different fabrication parameters impact the electrode mesostructure and the corresponding electrochemical response for graphite and NMC electrodes, in close comparison with in house experimental data. Finally, i discuss the impact of using innovative in house Virtual Reality tools to analyse the calculated and the imaged electrode mesostructures.
