On the other hand, multiscale modeling proves useful to analyze the macro, millimeter scale, too. This is quite intuitive insofar as we assume that the macroscale is fully informed by the physico-chemical processes lying beneath it, although taking into account the emergence of new properties from the combination of the simpler ones. While a fascinating approach, it seems incompatible with the screening of active materials (AMs) for electrodes: the chemical, structural and textural properties of AMs can indeed vary greatly and quickly become unmanageable in a multi-scale model.
