Preparation of Li₂S-AlI₃-LiI Composite Solid Electrolyte and Its Application in All-Solid-State Li-S Battery

Batteries, 2023
Novel (80Li2S − 20AlI3)·yLiI composite solid electrolytes (y = 5, 10, 15) were prepared by mechannochemical synthesis. XRD results showed that the pattern of 80Li2S − 20AlI3 was similar to that of AlI3, which means that Li2S was dissolved in AlI3 matrix ...

Catholyte Formulations for High-Energy Li–S Batteries [PDF]

The Journal of Physical Chemistry Letters, 2017
The sulfur electrode in LiS batteries suffers from rapid capacity loss and low efficiency due to the solubility of long chain polysulfides formed during discharge. Herein, we demonstrate the beneficial effect of original catholyte formulations containing redox active organyl disulfides (PhS2Ph) on the capacity utilization and retention as well as the ...

Single step tranformation of sulphur to Li₂S₂/Li₂S in Li-S batteries

, 2015
Lithium-sulphur batteries have generated tremendous research interest due to their high theoretical energy density and potential cost-effectiveness. The commercial realization of Li-S batteries is still hampered by reduced cycle life associated with the formation of electrolyte soluble higher-order polysulphide (Li2Sx, x = 4–8) intermediates, leading ...
