Abstract
Abstract The dissolvable polysulfides and sluggish Li 2 S conversion kinetics are acknowledged as two significant challenges in the application lithium–sulfur (Li–S) batteries. Herein, we introduce a dual-doping strategy to modulate the electronic structure of MoS 2 , thereby obtaining a multifunctional catalyst that serves as an efficient sulfur host. The W/V dual single-atom-doped MoS 2 grown on carbon nanofibers (CMWVS) demonstrates a strong adsorption ability for lithium polysulfides, suppressing the shuttle effects. Additionally, the doping process also results in the phase transition from 2H-MoS 2 to 1T-MoS 2 and generates sufficient edge sulfur atoms, promoting the charge/electron transfer and enriching…
