Classical and quantum simulations of a lithium ion solvated by a mixed Stockmayer cluster
The structure, classical thermodynamics, and ground state properties of a cluster comprised of a lithium ion surrounded by 106 points dipoles, are determined. Two types of Stockmayer particles, D-(N) and D-(T), with disparate polarities are chosen to reproduce the empirical room temperature properties of six molecules of a highly polar substance, namely nitromethane, and one hundred of a relatively less polar substance, tetrahydrofuran, to study the effects of additives in electrolyte mixtures typically used in lithium batteries. The global minimum features a pentacoordinated charge on the surface, while the ion is found between two solvation layers around room temperature.
