In article number 1802431 , Hongbin Lu and co‐authors demonstrate a multifunctional mediator based on a nickel cobalt double hydroxide (NiCo‐DH) composite for Li–S batteries. The NiCo‐DH plays an important role in suppressing the shuttle effect and accelerating the redox kinetics of LiPSs. The composite electrode can load high contents of sulfur (>85 wt%) and exhibit a superior capacity, ultrahigh rate performance, and ultralong life, with a decay rate of 0.015% per cycle.
