Strong Chemical Interaction between Lithium Polysulfides and Flame‐Retardant Polyphosphazene for Lithium–Sulfur Batteries with Enhanced Safety and Electrochemical Performance

Advances in Materials, 2021
The shuttle effect of lithium polysulfides (LiPS) and potential safety hazard caused by the burning of flammable organic electrolytes, sulfur cathode, and lithium anode seriously limit the practical application of lithium–sulfur (Li–S) batteries. Here, a

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.

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.

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 ...
