In order to test the accuracy and lithium diffusion mechanisms of predicted AutoBADDIE parameters on solid polymer electrolyte systems which depend strongly on by dihedral interactions of polymer backbones, we parameterized a class 1 interatomic potential for the polyethylene oxide (PEO)-lithium-TFSI electrolyte system. AutoBADDIE was benchmarked against simulations using class 1 interatomic potential parameters available in literature, namely, OPLS-AA parameters for the glyme parameters through LigParGen 9,19,24 combined with lithium and TFSI parameters from Doherty et al. (OPLS-AA+D). AutoBADDIE was also compared to simulations conducted by Brooks et al. using the OPLS2005 parameters,
