The commercialization of lithium-sulfur (Li-S) batteries is greatly hindered due to serious capacity fading caused by the polysulfide shuttling effect. Optimizing structural configuration, enhancing reaction kinetics sulfur cathode, and increasing areal loading are great significance for promoting commercial applications Li-S batteries. Herein, multifunctional scavengers based on nitrogen, co-doped carbon cloth (DCC), which supported flower-like MoS2 (1T-2H) decorated with BaMn0.9 Mg0.1 O3 perovskite particle (PrNP) nanotubes (CNTs), namely, DCC@MoS2 /PrNP/CNTs, delicately designed synthesized. physical confinement, chemical coupling, catalysis conversion active achieved simultaneously in this motif. Due these merits, as-fabricated self-supported /PrNP/CNTs/S manifests an excellent reversible 4.75 mAh cm-2 ultrahigh 5.2 mg at 50th cycle. outstanding cycling stability obtained upon 800 cycles a large 871 g-1 negligible rate 0.02% per cycle 1.0 C, suggesting its promising prospects success high-performance toward flexible electronic devices energy storage equipment.
