abstract = {The shuttling behavior and sluggish conversion kinetics of
the intermediate lithium polysulfides (LiPS) represent the
main obstructions to the practical application of
lithium–sulfur batteries (LSBs). Herein, a 1D π–d
conjugated metal–organic framework (MOF), Ni-MOF-1D, is
presented as an efficient sulfur host to overcome these
limitations. Experimental results and density functional
theory calculations demonstrate that Ni-MOF-1D is
characterized by a remarkable binding strength for trapping
soluble LiPS species. Ni-MOF-1D also acts as an effective
catalyst for S reduction during the discharge process and
Li2S oxidation during the charging process. In addition, the
delocalization of electrons in the π–d system of
Ni-MOF-1D provides a superior electrical conductivity to
improve electron transfer. Thus, cathodes based on Ni-MOF-1D
enable LSBs with excellent performance, for example,
impressive cycling stability with over $82\%$ capacity
retention over 1000 cycles at 3 C, superior rate performance
of 575 mAh g−1 at 8 C, and a high areal capacity of 6.63
mAh cm−2 under raised sulfur loading of 6.7 mg cm−2. The
strategies and advantages here demonstrated can be extended
to a broader range of π–d conjugated MOFs materials,
which the authors believe have a high potential as sulfur
hosts in LSBs.},
