Fluorinated Multi-Walled Carbon Nanotubes Coated Separator Mitigates Polysulfide Shuttle in Lithium-Sulfur Batteries [PDF]
Materials, 2023 Li-S batteries still suffer from two of the major challenges: polysulfide shuttle and low inherent conductivity of sulfur. Here, we report a facile way to develop a bifunctional separator coated with fluorinated multiwalled carbon nanotubes.

Size Effect for Inhibiting Polysulfides Shuttle in Lithium‐Sulfur Batteries
Small, 2023AbstractIt is undeniable that the dissolution of polysulfides is beneficial in speeding up the conversion rate of sulfur in electrochemical reactions. But it also brings the bothersome “shuttle effect”. Therefore, if polysulfides can be retained on the cathode side, the efficient utilization of the polysulfides can be guaranteed to achieve the ...

Small Methods, 2021
AbstractExhibiting high specific energy and low cost, lithium–sulfur batteries are considered promising candidates for the next‐generation battery. However, its wide applications are limited by the insulating nature of the sulfur, dissolution of polysulfide species, and large volume change of the sulfur cathode.

Graphdiyne (GDY), a new type of carbon material with an electron-rich conjugated structure, has been investigated as a separator coating layer to enhance the electrochemical performance of lithium-sulfur (Li-S) battery. Acetylenic bond (-C≡C-C≡C-) and benzene ring in the GDY coating layer are experimentally verified to reversibly attract the soluble ...

Probing Polysulfide Shuttle Effect in the Li-S Battery
ECS Meeting Abstracts, 2016The lithium-sulfur battery is a strong contender among the beyond Li-ion chemistries due to its superior capacity and energy density as compared to the conventional Li-ion cells. However, experimental evidences suggest that even the first discharge capacity is appreciably lower than the theoretical limit.
