After the slurry phase is formed, a dry electrode is generated by taking the slurry phase as the input structure and by removing the solvent particles. Then, an additional CGMD simulation is performed in order to equilibrate the dry electrode, by considering 'harder' LJ and GH parameters that mimic the formation of a more solid system, as explained in our previous work . Once the graphite dry electrode is formed, the structure is decorated with the remaining 10 wt.% of Si particles and further equilibrated with CGMD simulations. This last step contains two further approximations: the first one concerning the Si particle size and the second one related to the role of n-Si in affecting the slurry phase and the associated drying.
