Solid state lithium-sulfur (Li-S) batteries based on solid electrolytes- a brief review

Abstract

In this review manuscript different modification methods of electrolyte materials in view of their electrochemical properties for application in lithium-sulfur (Li-S) batteries have been presented. The fundamental understandings and technological innovations in lithium-sulfur batteries are essential for delivering high energy density, stable cyclability, and cost-effective energy storages with the growing demands in the applications of electrical vehicles and smart grids. Solid-state electrolytes (SSEs) are more promising than organic liquid electrolytes in terms of excellent safety in developing lithium anode as well as other high capacity cathode. The effects of novel electrolytes, such as gel polymer, solid polymer and solid ceramic electrolytes, garnet-type, perovskite-type, sodium superionic conductor (NASICON)-type, and Li superionic conductor (LISICON)-type materials, and sulfide glasses, are reviewed.
