abstract = {Single-ion conducting polymer electrolytes exhibit great
potential for next-generation high-energy-density Li metal
batteries, although the lack of sufficient molecular-scale
insights into lithium transport mechanisms and reliable
understanding of key correlations often limit the scope of
modification and design of new materials. Moreover, the
sensitivity to small variations of polymer chemical
structures (e.g., selection of specific linkages or chemical
groups) is often overlooked as potential design parameter.
In this study, combined molecular dynamics simulations and
experimental investigations reveal molecular-scale
correlations among variations in polymer structures and Li+
transport capabilities. Based on polyamide-based single-ion
conducting quasi-solid polymer electrolytes, it is
demonstrated that small modifications of the polymer
backbone significantly enhance the Li+ transport while
governing the resulting membrane morphology. Based on the
obtained insights, tailored materials with significantly
improved ionic conductivity and excellent electrochemical
performance are achieved and their applicability in LFP||Li
and NMC||Li cells is successfully demonstrated.},
