Revisiting the Role of Polysulfides in Lithium–Sulfur Batteries
Advanced Materials, 2018 AbstractIntermediate polysulfides (Sn, where n = 2–8) play a critical role in both mechanistic understanding and performance improvement of lithium–sulfur batteries. The rational management of polysulfides is of profound significance for high‐efficiency sulfur electrochemistry.
