Abstract

Soluble lithium polysulfides (Li2Sx, x ≥ 6) were used as co-salts/additives in an ether-based electrolyte for lithium sulfur (Li-S) batteries. By optimizing the concentration of the polysulfide species and the amount of electrolyte, the Li-S batteries show high and stable discharge capacity, outstanding rate capability, and exceptional cycling performance.
