Phosphorous pentasulfide (P 2 S 5 ) is discovered to be a novel electrolyte additive for high‐energy lithiumsulfur (Li‐S) batteries. P 2 S 5 passivates the surface of metallic lithium anodes, promotes the dissolution of Li 2 S, blocks the polysulfide shuttle, and thus enables long battery cycle‐life. On page 1064 , Chengdu Liang and co‐workers demonstrate that with a theoretical energy density of 2600 Wh/kg, which is about 3–5 times higher than that of the lithium‐ion batteries, Li‐S batteries are promising for the next generation of high‐energy batteries for large scale energy storage.
