The compression was performed by keeping the same FFs parameters value of the dried electrode mesostructure (Table in the Supplementary Information) and applying a moving plane to its top, which was moved down until reducing the electrode's thickness of 25% (with respect to its not-compressed state). This simulation was performed in LAMMPS and took approximately 20h by using one node (128 GB of RAM) composed of 2 processors (Intel® Xeon® CPU E5-2680 v4 @ 2.40GHz, 14 cores) on the MatriCs platform (Université de Picardie-Jules Verne).
