Abstract
Abstract The practical application of sulfur (S) cathodes in lithium‐sulfur (Li‐S) batteries is hindered by the shuttling of soluble lithium polysulfides (LiPSs) and sluggish sulfur redox kinetics. Addressing these challenges requires advanced catalytic host materials capable of trapping LiPSs and accelerating Li‐S redox reactions. However, single‐site catalysts struggle to effectively mediate the complex multi‐step and multi‐phase sulfur conversion processes. In this study, we present a novel dual‐site catalyst, Ni‐MoC‐NC, featuring nickel single atoms anchored to nitrogen sites (Ni‐N 4 ) within a carbon nitride (NC) matrix and molybdenum carbide (MoC) nanoclusters. Experimental and theoretical analyses…
