A key source of inaccuracy of Class 1 simulations of polymer electrolytes is the estimation of glass transition temperature (T g ), since T g correlates with chain mobility in polymers. The mismatch between experimental and Class-1 simulated T g is systematic and has been studied in detail by Afzal et. al. They simulated 315 polymers with reported experimental glass transition values and found a mean absolute error (MAE) of 81 C across the wide chemical space. Recent work on a novel polymer poly(pentyl malonate) (PPM) found that shifting the simulation temperature by a correction term corresponding to the mismatch between experimental and simulated T g mitigates most of the discrepancy in ionic conductivity between experiments and OPLS-AA MD simulations. In this work, we develop the platform HiTPoly (High-Throughput polymer simulations) for running MD simulations for polymer electrolytes with an integrated suite of transport and structure analysis tools (Figure ). We use it to benchmark polymer electrolyte simulations with the OPLS-AA force field for Li-ion battery applications across a wide chemical space.
