Finding the Perfect Match: Investigation of 1,2‐Diketone‐Based Materials for Use as Cathode Active Material in Rechargeable Magnesium Batteries

Small, Volume 22, Issue 46, 18 August 2026.
A novel and generally applicable early screening method for 1,2‐diketones via cyclic voltammetry and DFT computations identifies phenanthrenequinone as a suitable candidate as cathode active material for use in RMB. Its successful incorporation into a polymer enabled promising lithium and magnesium battery performance.

Suppressing Polysulfide Shuttle and Boosting Reaction Kinetics via UiO‐66‐SH‐Functionalized Separators for Lithium–Sulfur Batteries

Small Science, Volume 6, Issue 8, August 2026.
This work demonstrates a UiO‐66‐SH‐functionalized separator that boosts Li+ transport, thermal stability, polysulfide anchoring, and sulfur redox kinetics in Li–S batteries. As a result, the cell delivers an initial capacity of 821.3 mAh g−1 at 1 C and retains 521 mAh g−1 after 500 cycles.

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

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 ...

“Shuttle” in Polysulfide Shuttle: Friend or Foe? [PDF]

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.

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

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 ...

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.

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.

Minimizing Polysulfide Shuttle Effect in Lithium-Ion Sulfur Batteries by Anode Surface Passivation [PDF]

ACS Applied Materials & Interfaces, 2018
Lithium-ion sulfur batteries use nonlithium materials as the anode for extended cycle life. However, polysulfide shuttle reactions still occur on the nonmetal anodes (such as graphite and Si), and result in undesirable low Coulombic efficiency. In this work, we used Al2O3 layers coated by atomic layer deposition (ALD) technique to suppress the shuttle ...
