We used this workflow to rigorously benchmark the effects of interatomic potential parameterization on simulation results, in particular the point charge distribution of the TFSI anion in simulations of the prototypical SPE system. We first showed that AutoBADDIE is able to predict purely harmonic class 1 (OPLS-like) IP parameters that reproduce solvation and kinetic behavior of liquid carbonate and PEO-based SPE systems with good agreement to experiments and prior simulation literature. Then, we used AutoBADDIE to predict class 2 IP parameters (anharmonic covalent interactions as well as covalent cross terms and a softer Lennard-Jones stopping potential, like PCFF+ and COMPASS) for PEO to explore the effect of different nonpolarizable atomic charge partitions of TFSI geometries on resulting solvation and kinetic properties.
