Abstract

ConspectusSulfur, being lightweight, cost-effective, and offering a remarkably high lithium-ion storage capacity, has positioned lithium–sulfur (Li–S) batteries as promising candidates for applications that demand high energy density. These range from electric vehicles (EVs) to urban air mobility (UAM) systems. Despite this potential, Li–S batteries still face significant performance challenges, limiting their practical application. Chief among these challenges are the limited lifespan and low charge–discharge efficiency, predominantly caused by the dissolution of lithium polysulfide intermediate products formed during battery cycling in ether-based electrolytes. Moreover, sulfur and lithium sulfide, which…
