Implication

Experimental study demonstrates suppressed polysulfide shuttling and improved cycling in lithium–sulfur cells, suggesting an effective multifunctional separator strategy.

Key Points

Develop a multifunctional MXene/carbon nanotube/poly(ethylene oxide) heterostructured separator coating to mitigate polysulfide shuttling and accelerate sulfur redox kinetics in lithium–sulfur batteries.
Fabricated a composite separator interface combining polar MXene sheets, conductive carbon nanotubes, and poly(ethylene oxide).
Characterized charge-transfer resistance, potentiostatic Li2S deposition kinetics, and electrochemical performance during rate testing and long-term cycling.
The MX/CNT/PEO@PP separator reduced charge-transfer resistance from 175.9 Ω for pristine polypropylene to 15.7 Ω, representing a 91.1% reduction.
The cell achieved an initial discharge capacity of 1613 mAh g⁻¹ at 0.1 C, sustaining average capacities of 1331.1 mAh g⁻¹ at 0.1 C and 803.1 mAh g⁻¹ at 2 C.
Long-term cycling at 2 C demonstrated a retained capacity of 319.3 mAh g⁻¹ after 1000 cycles with an average decay rate of 0.064% per cycle.
