Attenuating the Polysulfide Shuttle Mechanism by Separator Coating

ChemPhysChem
Lithium-sulfur batteries have a high energy density but lack cycle stability to reach market maturity. This is mainly due to the polysulfide shuttle mechanism, i.e., the leaching of active material from the cathode into the electrolyte and subsequent ...

Developing A “Polysulfide‐Phobic” Strategy to Restrain Shuttle Effect in Lithium–Sulfur Batteries

Angewandte Chemie - International Edition, 2019
Inspired by hydrophobic interface, a novel design of "polysulfide-phobic" interface was proposed and developed to restrain shuttle effect in lithium-sulfur batteries. Two-dimensional VOPO4 sheets with adequate active sites were employed to immobilize the

Efficient polysulfide shuttle mitigation by graphene-lithium cobalt vanadate hybrid for advanced lithium-sulfur batteries

Journal of Electroanalytical Chemistry, 2021
Polysulfide shuttle is a major challenge to be addressed while designing lithium-sulfur batteries (LSBs) as it stagnates the overall performance of the system. The exploration of better material combinations is imperative to deal with the issue.

“Shuttle” in Polysulfide Shuttle: Friend or Foe?

The Journal of Physical Chemistry C, 2018
The polysulfide shuttle effect, where sulfur species reach the negative electrode surface and undergo chemical reduction, is believed to be a major bottleneck in lithium–sulfur chemistry.
