Sulfur-containing solid electrolytes are highly attractive to scientists and increasing day by day. Recently, Li7P3S11, Li10GeP2S12, Li11Si2PS12 have been of great interest in literature. The ionic conductivity these can even be reached a value 10-2 S/cm. For this purpose, Li7P3S11 electrolyte is synthesized mechanical alloying method for all-solid-state Lithium Sulfur batteries study. To do th...
