Unity of Opposites between Soluble and Insoluble Lithium Polysulfides in Lithium–Sulfur Batteries

Advanced Materials, 2022
AbstractRechargeable batteries based on Li–S chemistry show promise as being possible for next‐generation energy storage devices because of their ultrahigh capacities and energy densities. Research over the past decade has demonstrated that the morphology of lithium polysulfides (LPSs) in electrolytes (soluble or insoluble) plays a decisive role in ...

Unveiling the Reaction Mystery Between Lithium Polysulfides and Lithium Metal Anode in Lithium–Sulfur Batteries

Advanced Materials
AbstractLithium‐sulfur (Li–S) batteries are widely regarded as one of the most promising next‐generation high‐energy‐density energy storage devices. However, soluble lithium polysulfides (LiPSs) corrode Li metal and deteriorate the cycling stability of Li–S batteries.

Heterostructures Regulating Lithium Polysulfides for Advanced Lithium‐Sulfur Batteries

Advanced Materials, 2023
AbstractSluggish reaction kinetics and severe shuttling effect of lithium polysulfides seriously hinder the development of lithium‐sulfur batteries. Heterostructures, due to unique properties, have congenital advantages that are difficult to be achieved by single‐component materials in regulating lithium polysulfides by efficient catalysis and strong ...

Electrochemistry of a lithium electrode in lithium polysulfide solutions

Russian Journal of Electrochemistry, 2008
The effect of lithium polysulfides on the cycling of a lithium electrode and the corrosion rate of lithium cathodic deposits in sulfolane electrolytes is studied. Lithium polysulfides are found to affect the shape of polarization curves, the overpotential of electrode processes, and the cycling time.

Self‐Assembled Networks for Regulating Lithium Polysulfides in Lithium‐Sulfur Batteries

ChemSusChem, 2022
AbstractInhibiting the shuttle effect caused by soluble lithium polysulfides (LiPSs) is of importance for lithium‐sulfur (Li−S) batteries. Here, a strategy was developed to construct protective layers by self‐assembly networks to regulate the LiPSs. 2,5‐Dichloropyridine (25DCP) holds two kinds of functional groups.

Chemical Immobilization Effect on Lithium Polysulfides for Lithium–Sulfur Batteries

Small, 2017
AbstractDespite great progress in lithium–sulfur batteries (LSBs), great obstacles still exist to achieve high loading content of sulfur and avoid the loss of active materials due to the dissolution of the intermediate polysulfide products in the electrolyte.
