Sc/Mg Co-Doping in Na₃Zr₂Si₂PO₁₂ Solid-State Electrolytes Enables Outstanding Performance of Sodium Metal Batteries.

ABSTRACT: All solid-state sodium metal batteries offer a transformative opportunity for more sustainable energy storage, with the potential to significantly improve both energy density and safety compared to conventional sodium-ion batteries. However, their practical application is hindered by challenges such as dendrite formation and limited ion conductivity. In this study, a novel strategy is proposed in which Sc³⁺ and Mg²⁺ dopants are directly introduced into the Na₃Zr₂Si₂PO₁₂ solid-state electrolyte (NZSP SSE) to optimize composition and regulate interfacial chemistry. The resulting co-doped electrolyte, Na_3.7Zr_1.45Sc_0.4Mg_0.15Si₂PO₁₂ (NSZSP-0.15Mg), exhibits a signi
