Rational synthesis of MnO2@CMK/S composite as cathode materials for lithium-sulfur batteries

Journal Article


Abstract


  • Lithium–sulfur batteries with a high energy density are promising energy storage devices. The realization of lithium–sulfur batteries is mainly hindered by the dissolution of the intermediate polysulfides. In the present work, a new physical and chemical entrapment method of the polysulfides has been proposed, which used CMK-3 as the carbon scaffolds and a MnO2 coating layer for chemisorption. Such a bi-functional framework provides efficient trapping for the polysulfides, achieving a reversible capacity of 600 mAh g−1 after 100 cycles at 0.1 C with a 73.4 wt% sulfur loading in the composite.
