Title: Stabilizing the Interface between Sodium Metal Anode and Sulfide-Based Solid-State Electrolyte with an Electron-Blocking Interlayer

Abstract

Sulfide-based Na-ion conductors are promising electrolytes for all-solid-state sodium batteries (ASSSBs) because of high ionic conductivity and favorable formability. However, no effective strategy has been reported for long-duration Na cycling with sulfide-based electrolytes because of interfacial challenges. Here we demonstrate that a cellulose–poly(ethylene oxide) (CPEO) interlayer can stabilize the interface between sulfide electrolyte (Na 3SbS 4) and Na by shutting off the electron pathway of the electrolyte decomposition reaction. In conclusion, we achieved stable Na plating/stripping for 800 cycles at 0.1 mA cm –2 in all-solid-state devices at 60 °C.
