To better understand the initial stages of SEI formation on the examined surface models, it is important to consider the potential presence of water within the interfacial region, as it can significantly affect the stability and arrangement of the adsorbed ion species. To address this, we conduct new simulations in the presence of water molecules. In our analysis, we assume that the salt concentration in the bulk electrolyte is sufficiently high to exclude the presence of free water molecules and free ions, as expected in the WiS regime . Consequently, only water molecules within the solvation shells of contact ion pairs and solvent-separated ion pairs can approach the electrode surface and contribute to SEI formation. For the NaOTF WiS electrolyte, this assumption corresponds to a salt concentration of approximately 9.25 𝑚 or higher, as determined in our previous research .
