In article 1400227, Q. Zhang and co‐workers demonstrate the enhanced cycling stability of lithium‐sulfur batteries by employing nitrogen‐doped carbon nanotubes as heterogeneous conductive scaffold to trap all kinds of sulfur species. The polysulfides and Li 2 S are strongly coupled with an electro‐rich pyridinic nitrogen and the carbon surface around the quaternary nitrogen, which significantly suppresses the irreversible loss of capacity.
