Illuminating Polysulfide Distribution in Lithium Sulfur Batteries; Tracking Polysulfide Shuttle Using <i>Operando</i> Optical Fluorescence Microscopy. [PDF]

ACS Appl Mater Interfaces
High-energy-density lithium sulfur (Li-S) batteries suffer heavily from the polysulfide shuttle effect, a result of the dissolution and transport of intermediate polysulfides from the cathode, into the electrolyte, and onto the anode, leading to rapid cell degradation.

Tunnel Structure Enhanced Polysulfide Conversion for Inhibiting “Shuttle Effect” in Lithium-Sulfur Battery

Nanomaterials, 2022
The Lithium sulfur (Li-S) battery has a great potential to replace lithium-ion batteries due to its high-energy density. However, the “shuttle effect” of polysulfide intermediates (Li2S8, Li2S6, Li2S4, etc.) from the cathode can lead to rapid capacity ...

Selective catalysis remedies polysulfide shuttling in lithium-sulfur batteries [PDF]

Advanced Materials, 2020
Abstract The shuttling of soluble lithium polysulfides between the electrodes leads to serious capacity fading and excess use of electrolyte, which severely bottlenecks practical use of Li-S batteries. Here selective catalysis is proposed as a fundamental remedy for the consecutive solid-liquid-solid sulfur redox reactions. The proof-of-concept

A polysulfide radical anions scavenging binder achieves long‐life lithium–sulfur batteries

Battery Energy, 2022
Fast capacity decay caused by the polysulfide shuttle is the primary cause to impede the practical application of lithium–sulfur (Li–S) batteries. The polysulfide shuttle involves the evolution of polysulfide dianions (Li2Sx, x = 3–8) and radical anions (
