A Review on Engineering Design for Enhancing Interfacial Contact in Solid-State Lithium–Sulfur Batteries

Abstract

Highlights The engineering design principles for enhancing interfacial contact between the electrodes (Li anodes and S cathode) and solid-state electrolytes in solid-state Li–S batteries are classified and discussed. Research progresses of experimental strategies for reducing interfacial impedance in solid-state Li–S batteries are summarized. Challenges and future perspectives of rational interfacial strategies in solid-state Li–S batteries are highlighted.
