Overview

Experimental study demonstrates enhanced polysulfide conversion and cycling stability using MoO2-MoS2 separator coatings in lithium-sulfur batteries, indicating a viable design for high-energy...

Key Points

To develop a functional separator coating with high-density exposed catalytic heterointerfaces that suppresses polysulfide shuttling and accelerates redox kinetics in lithium–sulfur batteries.
Synthesized a composite containing few-layer MoS2 nanoflakes on polar MoO2 integrated with carbon nanotubes as a functional separator coating.
Characterized polysulfide conversion kinetics and reaction reversibility using Li2S nucleation measurements and in situ X-ray diffraction.
The MoO2–MoS2 heterointerfaces provided balanced polysulfide adsorption and pronounced charge redistribution, accelerating reaction intermediate conversion and Li2S nucleation.
Li–S cells achieved an initial specific capacity of 1236 mAh g⁻¹ at 0.2 C and retained 475 mAh g⁻¹ after 1000 cycles at 1 C.
