Synergic effect of CaI₂ and LiI on ionic conductivity of solution-based synthesized Li₇P₃S₁₁ solid electrolyte.

ABSTRACT: Li₇P₃S₁₁ doped with CaX₂ (X = Cl, Br, I) and LiI solid electrolytes were successfully prepared by liquid-phase synthesis using acetonitrile as the reaction medium. Their structure was investigated using XRD, Raman spectroscopy and SEM-EDS. The data obtained from complex impedance spectroscopy was analyzed to study the ionic conductivity and relaxation dynamics in the prepared samples. The XRD results suggested that a part of CaX₂ and LiI incorporated into the structure of Li₇P₃S₁₁, while the remaining part existed at the grain boundary of the Li₇P₃S₁₁ particle. The Raman peak positions of PS₄^3- and P₂S₇^4- ions in sam
