Ultra-lightweight Ti3C2T MXene modified separator for Li–S batteries: Thickness regulation enabled polysulfide inhibition and lithium ion transportation

, 2020
The practical application of lithium–sulfur (Li–S) batteries is limited by the easy dissolution of polysulfides in the electrolyte, resulting in the lithium polysulfide (LPS) shuttle effect.

Formation of Polysulfides in Aqueous Solution

Environmental Letters, 1973
Abstract Polysulfides are found to be the reaction intermediates in the oxygenation of aqueous sulfide. The pH dependence of the reaction rates is directly related to the formation of polysulfides. In general, the peak of polysulfide concentrations fall within the range pH 7.0 ± 0.4, and decrease drastically in both acidic and alkaline solutions. Under
