      abstract     = {The shuttling behavior and sluggish conversion kinetics of
                      intermediate lithium polysulfides (LiPS) represent the main
                      obstacles to the practical application of lithium–sulfur
                      batteries (LSBs). Herein, an innovative sulfur host is
                      proposed, based on an iodine-doped bismuth selenide
                      (I-Bi2Se3), able to solve these limitations by immobilizing
                      the LiPS and catalytically activating the redox conversion
                      at the cathode. The synthesis of I-Bi2Se3 nanosheets is
                      detailed here and their morphology, crystal structure, and
                      composition are thoroughly. Density-functional theory and
                      experimental tools are used to demonstrate that I-Bi2Se3
                      nanosheets are characterized by a proper composition and
                      micro- and nano-structure to facilitate Li+ diffusion and
                      fast electron transportation, and to provide numerous
                      surface sites with strong LiPS adsorbability and
                      extraordinary catalytic activity. Overall, I-Bi2Se3/S
                      electrodes exhibit outstanding initial capacities up to 1500
                      mAh g−1 at 0.1 C and cycling stability over 1000 cycles,
                      with an average capacity decay rate of only $0.012\%$ per
                      cycle at 1 C. Besides, at a sulfur loading of 5.2 mg cm−2,
                      a high areal capacity of 5.70 mAh cm−2 at 0.1 C is
                      obtained with an electrolyte/sulfur ratio of 12 µL mg−1.
                      This work demonstrated that doping is an effective way to
                      optimize the metal selenide catalysts in LSBs.},
