Investigation of lithium polysulfide diffusion and speciation in solid-state hybrid electrolyte.

Lithium/Sulfur batteries with solid electrolyte are good candidates to replace Li-ion batteries. In Li-ion the liquid electrolytes are flammable by nature and moving to a safe solid-state one is of interest. In addition, solid electrolytes are foreseen as a solution to avoid the main drawback of such batteries, i.e. polysulfide shuttle. During cycling, the soluble products, Li polysulfide (Li2Sx, 2
