Current Status and Future Prospects of Solid‐State Lithium–Sulfur Batteries: A Focus on Reaction and Interface Engineering (Adv. Energy Mater. 8/2026)

Li–S Batteries In article number 2501926, Guoxiu Wang, Zhenhua Sun, Feng Li, and co-workers provide an in-depth review on solid-state lithium-sulfur batteries from perspectives of reaction and interface. Kinetics and reversibility of sulfur conversion reactions, and mechanisms underlying lithium dendrite formation are introduced. The across-interface e−/Li+ transport, and the stability of solid electrolyte/lithium interfaces are concerned. Moreover, quantified high-energy-density parameters pave the way for solid-state lithium-sulfur batteries meeting commercial demands.
