Summary: Solid-state sodium metal batteries are highly attractive for large-scale energy storage due to their high safety, high energy density, and low cost. However, the practical application has been hindered by large interfacial resistance and sodium dendrite growth. In this study, a modified ultrasound welding technique was proposed to improve the interface between Na anodes and Au-metalized Na3Zr2Si2PO12 electrolytes. The results showed that the modified interface exhibited low interfacial resistance and strong dendrite inhibition ability, enabling stable cycling and high current density. Considering the importance of energy density, a full battery with a solid-state electrolyte and Na3V2(PO4)(3) cathode achieved high energy density and power density. The assembly of a pouch-type solid-state sodium metal full battery demonstrated the potential of this strategy to engineer low-resistance and highly stable interfaces for high-energy/density solid-state sodium metal batteries.
