The implicit solvent model treats the solvent as a continuous, homogeneous, and isotropic medium characterized by a static dielectric constant, ϵ. Due to the clustering effect of Li + and TFSI -ions 36 (see Fig. ), our study focuses on varying the dielectric constant within two simplified systems: (I i ) a single TBT with one LiTFSI, and (II i ) 2 TBTs with one LiTFSI, where superscript i represents the implicit solvent environment. We examined three dielectric constants of 10.6, 6.0, and 8.0, representative of DME, DOL, and a mixture of DME and DOL 37 (see Table ). The force field for Li + and TFSI -ions are based on Dang et al. and Lopes et al., respectively.
