MD simulations based on classical potentials are limited in their transferability and their ability to describe charge transfer effects. First-principles methods which treat the electrons quantum mechanically do not have such limitations. Static quantum calculations using cluster models , do not, however, include the effect of the overall liquid environment.Thus, it is imperative to use classical potentials to sample the phase space of the liquid environment. Although several scientific reports of Li + ion solvation in pure and mixed carbonate systems have been reported so far as mentioned above, however, none has been reported on the liquid structure of Li + ion solvation in mixed [EMI][TFSI] and EC/DMC co-solvent systems. The present work is, therefore, the first such report on the liquid structure of Li + ion solvation in immodazolium based IL/carbonate mixed systems, where the Li + ion solvation effects due to the individual cationsolvent and solvent-solvent interactions, and the resulting EC/DMC concentration effects on the local solvation structure are extensively discussed.
