Sulfurized polyacrylonitrile (SPAN) is investigated as a cathode for room‐temperature Na–S batteries in ether‐based electrolytes under controlled discharge depths. Depth‐of‐discharge‐dependent structural evolution reveals that deep discharge below 1.0 V destabilizes SPAN structure, alters polysulfide equilibria, and promotes sodium dendrite formation ...

Homogeneous Redox Mediators Applied to Li–S Batteries
Redox mediators can improve the needed sulfur‐based species conversions in several Li–S battery designs. Here, we evaluate four redox mediators, two metallocenes (DmFc, DmMn) and two quinones (AQ, NHQ), to show how their efficacy and practical promise depend on both design, species, and electrolyte composition, and especially how solvation controls the

Intraparticular Heterogeneity Limits Capacity in Lithium–Sulfur Batteries With Carbonate Electrolyte
Cryo‐electron‐microscopy and electrochemical testing reveal that the cathode‐electrolyte interphase in Li–S batteries with carbonate electrolytes forms heterogeneously across carbon particles. This intraparticle heterogeneity limits capacity and rate performance, highlighting the critical role of particle size and cathode‐electrolyte interphase ...

The degradation of all‐solid‐state batteries stems from coupled chemo‐electro‐mechanical interactions across materials, interfaces, and cell structure. This review systematically analyzes failure mechanisms involving material instability, interfacial contact loss, and stress evolution, offering guidance for battery design.
