An equilibration run was then performed for a total of 10 7 timesteps, corresponding to a real time of 10 -4 s. This duration was chosen to ensure effective Brownian diffusion and aggregation of the active material particles, which exhibit self diffusion times in the range of 10 -4 s. Following this, we simulate the drying of the electrode, by uniformly compressing the simulation domain at a constant rate to ensure the system is held at a low Péclet number regime. This is done to ensure the simulation represents bulk drying, while preventing the stratification of colloidal particles which is common at high drying rates . Videos depicting the equilibration and drying processes can be found in the Supporting Information.
