Radial distribution function There are two peaks for polarizable and OPLS force fields, and by charge rescaling the first peak diminishes and the second peak disappears. The first peak position from polarizable force field model is smaller (1.8 Å) than the peak position of EC/EMC, and ion-pairs are in contacts with Li ions are observed, whereas for non-polarizable force field the first peak position shifts to higher value (2.15 Å), so anions are sitting at marginal positions compared with EC/EMC. Also the height of first peak is smaller, hence more contacts form in polarizable force field than both variants of non-polarizable force field.
