Etched ion-track membranes as tailored separators in Li-S batteries.

Lithium-sulfur (Li-S) batteries are considered a promising next generation alternative to lithium-ion batteries for energy storage systems due to its high energy density. However, several challenges, such as the polysulfide redox shuttle causing self-discharge of the battery, remain unresolved. In this paper, we explore the use of polymer etched ion-track membranes as separators in Li-S batteries to mitigate the redox shuttle effect.
