Analysis on the first solvation shell of lithium ions under the different IPs elucidates further differences due to the charge distribution of TFSI. First, lithium under the France-Lanord parameterization has an unstructured interaction with TFSI as seen in Figure and also has a lower overall oxygen coordination number relative to the simulations using AutoBADDIEderived PEO parameters as seen in Figure . Additionally, the amount that lithium ions coordinate to TFSI remains relatively constant as salt concentration increases in the FL simulations.
