Abstract

We performed molecular dynamics (MD) simulations of ionic liquids composed of 1-butyl-3-methylimidazolium ([bmim]) cation with PF6, NO 3 and Cl anions to determine their static and dynamic properties. Large-scale simulation of 4096 ion pairs (131,072 particles in [bmim]PF 6) was performed to estimate the system-size dependence of the static and dynamic properties. The diffusion constant, which is 100 times smaller than that of a normal liquid such as water, was estimated from long-time simulations. We also performed non-equilibrium MD simulations to determine the electrical conductivity. We obtained a nonlinear relationship between the electrical current and external electric field strength.
