摘要
Lithium–Sulfur Batteries
In article number 2205284, Xue-Qiang Zhang, Qiang Zhang, and co-workers demonstrate that by weakening the solvating power of the solvents, lithium polysulfides can be encapsulated to inhibit the parasitic reactions on lithium-metal anodes. The large steric hindrance of the fluorohydrocarbon chains and the electron-withdrawing–CF2–segments endow 1,1,2,2-tetrafluoroethyl-2,2,3,3-tetrafluoropropyl ether with prominently weak solvating power, similar to a submarine, to tightly encapsulate lithium polysulfides and achieve long-cycling lithium–sulfur batteries.
