In this study, we investigated the effect of DFT density functionals and dispersion correction on an imidazolium-based dicationic ionic liquid (DIL) using molecular dynamics simulations. To achieve this purpose, the electronic structures, as well as the structural and dynamical properties of [C(mim)][NTF] DIL, were obtained using the BLYP and PBE functionals, both with and without D3-correction, and the results were compared with experimental values. Radial distribution functions and structure factors revealed that applying D3-correction increases the interaction between the anion and hydrogen atoms of the rings and side chains.

Although disubstituted imidazolium cation is sterically crowded, hundreds of ionic liquids based on this cation have been reported as electrolytes for energy storage devices. In contrast to disubstituted imidazolium, non-substituted imidazolium is uncrowded sterically and has not yet been investigated as an electrolyte, to the best of our knowledge. Hence, imidazolium hydrogen sulfate [Imi][HSO], in mixture with water, was studied as an electrolyte for PANI-based electrode materials.

A new approach for the efficient parametrization of the polarizable ionic liquid potential AMOEBA-IL and its application to develop parameters for imidazolium-based cations is presented. The new approach relies on the development of parameters for fragments that can be transferred to generate new molecules. The parametrization uses the original AMOEBA-IL parametrization approach, including the use of Gaussian electrostatic model-distributed multipoles (GEM-DM) for the permanent multipoles and approximation of the van der Waals parameters using quantum mechanics energy decomposition analysis (QM-EDA) data.
