Polysulfide Speciation and Migration in Catholyte Lithium−Sulfur Cells [PDF]

open access: yesChemPhysChem, 2022
AbstractSemi‐liquid catholyte Lithium−Sulfur (Li−S) cells have shown to be a promising path to realize high energy density energy storage devices. In general, Li−S cells rely on the conversion of elemental sulfur to soluble polysulfide species. In the case of catholyte cells, the active material is added through polysulfide species dissolved in the ...

Reaction between Lithium Anode and Polysulfide Ions in a Lithium–Sulfur Battery [PDF]

open access: yesChemSusChem, 2016
AbstractThe reaction between polysulfides and a lithium anode in a Li–S battery was examined using HPLC. The results demonstrated that the polysulfide species with six sulfur atoms or more were reactive with regard to lithium metal. Although the reaction can be greatly inhibited by the addition of LiNO3 in the electrolyte, LiNO3 cannot form a stable ...
