Sulfur-containing solid electrolytes are highly attractive to scientists and are increasing day by day. Recently, Li7P3S11, Li10GeP2S12, and Li11Si2PS12 solid electrolytes have been of great interest in literature. The ionic conductivity of these electrolytes can even be reached a value of 10-2 S/cm. For this purpose, Li7P3S11 solid electrolyte is synthesized by mechanical alloying method for all-solid-state Lithium Sulfur batteries in this study. To do this, Li2S and P2S5 ingredients were mixed in a ball mill at certain stoichiometric ratios. The crystallization temperatures of the obtained powders were determined by the DSC thermal analysis method, and they were crystallized under a protective atmosphere at the appropriate crystallization temperature. Then, the obtained powders, very sensitive to the open atmosphere, were subjected to XRD and Raman analysis with a custom-made trap. Structurally characterized powders were electrochemically tested with electrochemical impedance spectroscopy and cyclic voltammetry analyses in a special solid-state cell. It has been observed that the results are compatible with the literature, and it has been determined that the synthesized electrolyte can be used as a suitable candidate for lithium sulfur batteries.
