Research topics from publications: Oxygen Dopants in MoS2 Catalysts as Dual Anchors for a Lithium Polysulfide Chain to Accelerate Conversion to Solid Li2S: A Strategy to Mitigate the Shuttle Effect in Li–S Batteries. Representative work: The development of lithium–sulfur batteries (LSBs) is hindered by the solubility of polysulfide intermediates. Herein, we synthesized oxygen-doped MoS2 on a highly conductive CNT as a cathode material for LSBs. The spaced oxygen dopants on the catalyst surface enable Li polysulfide chains to adsorb parallel to the catalyst surface. This configuration restricts solubility and accelerates the conversion of soluble Li polysulfides to insoluble Li2S. Therefore, the Mo(S-O)2/CNT cathode demonstrates an impressive discharge capacity (1410.4 mAh g–1 at 0.2 C and 880.3 mAh g–1 at 2 C) along with exceptional cycle stability, retaining 62.7% capacity after 100 cycles at 0.2 C and showing a low decay r
