It has been even used for the simulation of non-standard manufacturing methods such as solvent free extrusion or cold pressing. The digital reconstruction of the 3-D model of an electrode can be done by four differentiated approaches. The first one goes through the simulation of the complete manufacturing process including the formulation and drying. This approach is appropriate for understanding the relationship between microstructure parameters and manufacturing process, it is relatively computationally expensive, which makes it difficult to explore a diversity of parameters.
