“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. The importance of this phenomenon is often judged based on phenomenological arguments, which do not account for mesoscale complexations.

Polysulfide-Scission Reagents for the Suppression of the Shuttle Effect in Lithium–Sulfur Batteries

ACS Nano, 2017
Lithium-sulfur batteries have become an appealing candidate for next-generation energy-storage technologies because of their low cost and high energy density. However, one of their major practical problems is the high solubility of long-chain lithium polysulfides and their infamous shuttle effect, which causes low Coulombic efficiency and sulfur loss ...

Attenuating the Polysulfide Shuttle Mechanism by Separator Coating

ChemPhysChem
AbstractLithium‐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 side reactions.

Electrocatalytic Polysulfide Traps for Controlling Redox Shuttle Process of Li–S Batteries

Journal of the American Chemical Society, 2015
Stabilizing the polysulfide shuttle while ensuring high sulfur loading holds the key to realizing high theoretical energy of lithium-sulfur (Li-S) batteries. Herein, we present an electrocatalysis approach to demonstrate preferential adsorption of a soluble polysulfide species, formed during discharge process, toward the catalyst anchored sites of ...

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

Angewandte Chemie - International Edition, 2019
AbstractInspired 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 polysulfides through the formation of a V−S bond.
