Stepwise Pressure Effects on Sulfide Solid-State Battery Interface: How Pre-Pressing, Final Pressing, and Operating Pressure Each Control LPSCl Interfacial Stability
Abstract Sulfide solid-state batteries assembly requires three distinct pressure stages, not one. Yan et al. (JCIS 2026) demonstrate that treating “assembly pressure” as a single parameter misses critical interfacial physics. Their...
