MoS₂ quantum dot-decorated CNT networks as a sulfur host for enhanced electrochemical kinetics in advanced lithium-sulfur batteries.

ABSTRACT: The slow redox kinetics and shuttle effect of polysulfides severely obstruct the further development of lithium-sulfur (Li-S) batteries. Constructing sulfur host materials with high conductivity and catalytic capability is well acknowledged as an effective strategy for promoting polysulfide conversion. Herein, a well-designed MoS₂ QDs-CNTs/S@Ni(OH)₂ (labeled as MoS₂ QDs-CNTs/S@NH) cathode was synthesized via a hydrothermal process, in which conductive polar MoS₂ quantum dot-decorated carbon nanotube (CNT) networks coated with an ultrathin Ni(OH)₂ layer acted as an efficient electrocatalyst. MoS₂ QD nanoparticles with a high conductivity and catalytic nature can enhance the kinetics of polysulfide conversion, expedite
