A sulfur electrode exhibiting strong polysulfide chemisorption using a porous N, S dual-doped carbon is reported. The synergistic functionalization from the N and heteroatoms dramatically modifies electron density distribution leads to much stronger binding. X-ray photoelectron spectroscopy studies combined with ab initio calculations reveal Li(+) -N Sn (2-) -S interactions. electrodes exhibit an ultralow capacity fading of 0.052% per cycle over 1100 cycles.
The lithium‐sulfur battery is a compelling energy storage system because its high theoretical density exceeds Li‐ion batteries at much lower cost, but applications are thwarted by capacity decay caused the polysulfide shuttle.
