Results of molecular dynamics simulations using many-body polarizable APPLE&P force field are presented for 34 ionic liquids covering a broad range of cations and anions. The relation between ionic liquid transport properties (ion self-diffusion coefficient and conductivity), thermodynamic properties (molar volume and heat of vaporization) and cation-anion binding energies are presented. Development of the nonpolarizable united atom force field for alkylpyrrolidinium and tetraalkyl ammonium-based ionic liquids is reported. The nonpolarizable force field yielded higher activation energy for ion transport as a function of temperature and slightly lower heat of vaporization compared to MD simulation results using polarizable APPLE&P force field. Interfacial properties of N-methyl-N-propylpyrrolidinium bis(trifluoromethane)sulfonyl imide ([pyr_(13)][TFSI]) near a graphite electrode and confined in nanopores have been studied as a function temperature, electrode potential or the size of the nanopore. A camel shaped differential capacitance as a function of applied potential is reported for the flat surface electrode and is correlated with the changes of the interfacial structure.
