Abstract Sodium metal battery is considered as one of the most promising energy storage/conversion devices due to their high density, and abundant sodium reserves. However, its development hampered by limited metallic utilization detrimental dendrite growth ascribed unstable, fragile solid electrolyte interphase (SEI). Here, stable modulus SEI constructed with a component thin dense layer Na‐ion conductive Na 2 SiO 3 . It in situ formed reaction between anode fish‐skin structure separator,...
