That said, our DEM model still provides a viable methodology and a useful framework for simulating and analyzing the SF extrusion process parameters for the manufacturing of filaments for 3D printing LIB electrodes. We underline that this extrusion model can be also relevant to produce virtual filaments afterwards used in a DEM model simulating a dry coating, within a SF LIB electrode manufacturing workflow. Our model also provides valuable insights on the interaction between process parameters, material properties and microstructure properties. This modeling work has strong potential to enable process parameters optimization and filament properties to be predicted. It also paves the way towards a digital twin concept for real-time control of a physical extruder, as we are going to demonstrate further in an incoming work. Optimization of the extrusion process will provide continued impetus for the development of more efficient, environmentally sustainable, and higher performing battery cell electrodes.
