Discretized Analysis of Polysulfide Shuttle Dynamics in Lithium-Sulfur Batteries

Journal of The Electrochemical Society
The polysulfide shuttle effect remains a fundamental challenge in lithium-sulfur batteries, particularly for high-energy-density applications where conventional mitigation strategies prove insufficient. Here, we introduce a state-resolved methodology for quantifying shuttle current by analyzing Coulombic efficiency across discretized charging blocks ...

Electrolyte-Mediated Transport and Polysulfide Shuttle in Lithium–Sulfur Batteries

ECS Meeting Abstracts
Electrolyte composition critically governs the electrochemical performance of lithium–sulfur (Li–S) batteries. In this work, we investigate the coupled effects of electrolyte concentration and electrolyte-to-sulfur (E/S) ratio on electrochemical performance, with a specific focus on the polysulfide shuttle effect and its impact on active material ...

Locally Confined Polysulfide-Reactive Electrolytes for Shuttle-Free Sodium–Sulfur Batteries

Journal of the American Chemical Society
Sodium-sulfur batteries promise high-energy-density and sustainable electrochemical energy storage but suffer from uncontrolled polysulfide dissolution and high sodium reactivity. These challenges fundamentally originate from poor electrolyte-electrode compatibility.
