In situ construction of a stable interface induced by the SnS2 ultra-thin layer for dendrite restriction in a solid-state sodium metal battery

Ultra-thin SnS₂ was fabricated on the surface of Na₃Zr₂Si₂PO₁₂ electrolyte to in situ construct a stable mix-ion-electron conductor interface layer consists of Na-Sn alloy and Na₂S during cycling for Na dendrite restriction.
