Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201502467-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>A sulfur electrode</bold> exhibiting strong polysulfide chemisorption using a porous N, S dual‐doped carbon is reported. The synergistic functionalization from the N and S heteroatoms dramatically modifies the electron density distribution and leads to much stronger polysulfide binding. X‐ray photoelectron spectroscopy studies combined with ab initio calculations reveal strong Li⁺–N and S<italic>_n</italic>²⁻–S interactions. The sulfur electrodes exhibit an ultralow capacity fading of 0.052% per cycle over 1100 cycles. <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgkhm1fbb5" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
