A Polysulfide‐Immobilizing Polymer Retards the Shuttling of Polysulfide Intermediates in Lithium–Sulfur Batteries

Advanced Materials, 2018
AbstractLithium–sulfur batteries are regarded as one of the most promising candidates for next‐generation rechargeable batteries. However, the practical application of lithium–sulfur (Li–S) batteries is seriously impeded by the notorious shuttling of soluble polysulfide intermediates, inducing a low utilization of active materials, severe self ...

Can Metal Cations Electrocatalyze Sulfur Redox Reaction and Suppress Polysulfide Shuttle?

Batteries & Supercaps, 2023
AbstractIn lithium‐sulfur (Li−S) batteries, sulfur undergoes various changes. It switches between cyclic structure and linear structure. The charge on the sulfur varies between a neutral state and a negative charge‐bearing state. Due to these changes, the sulfur/polysulfide dissolves in the battery electrolyte.

Controlling Polysulfide Shuttling in Lithium-Sulfur Batteries

ECS Meeting Abstracts, 2015
Most electric cars run on rechargeable lithium-ion batteries, a pricey technology that accounts for more than half of the vehicle's total cost [1]. The development of renewable, low cost, high performance energy technologies is a key scientific challenge.

Polysulfides shuttling remedies by interface-catalytic effect of Mn3O4-MnPx heterostructure

Energy Storage Materials, 2021
Abstract Lithium-sulfur batteries (Li-S batteries) have attracted considerable attentions for the low cost and high theoretical energy density of sulfur. However, the Li-S batteries often undergo rapid degradation due to the severe “shuttle effect”, sluggish redox kinetics, and the insulator nature of sulfur.

Graphdiyne-Modified Polyimide Separator: A Polysulfide-Immobilizing Net Hinders the Shuttling of Polysulfides in Lithium–Sulfur Battery

ACS Applied Materials & Interfaces, 2019
Graphdiyne (GDY), a new type of carbon material with an electron-rich conjugated structure, has been investigated as a separator coating layer to enhance the electrochemical performance of lithium-sulfur (Li-S) battery. Acetylenic bond (-C≡C-C≡C-) and benzene ring in the GDY coating layer are experimentally verified to reversibly attract the soluble ...

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.

Probing Polysulfide Shuttle Effect in the Li-S Battery

ECS Meeting Abstracts, 2016
The lithium-sulfur battery is a strong contender among the beyond Li-ion chemistries due to its superior capacity and energy density as compared to the conventional Li-ion cells. However, experimental evidences suggest that even the first discharge capacity is appreciably lower than the theoretical limit.

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 ...
