摘要

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 Li2S 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.
