Atomistic insights into fluoride ion conduction in Ba1−xSnxF2 from 19F PFG-NMR studies (opens in new tab)

Currently, a variety of solid F− conductors are being considered as potential electrolytes for the development of all-solid-state fluoride-ion batteries. Among those, PbSnF4 type solid F− conductors are promising due to their high ionic conductivity at ambient temperatures. Here we have developed a PbSnF4-type solid electrolyte Ba1−xSnxF2 (x = 0.54) (BSF), which exhibits high ionic conductivity of approximately 9 × 10−3 Scm−1 at 298 K. In this study, we investigated the origin of its high con...
