Abstract

A high-strength ceramic-gel electrolyte enables efficient stress transfer, achieving a compressive strength of 20.1 MPa (20 times that of conventional gel electrolytes) while maintaining excellent ionic conductivity and effectively suppressing sodium dendrite growth. The Na₃Zr₂Si₂PO₁₂ framework acts as a thermal barrier, imparting the ceramic-gel composite electrolytes with superior flame retardancy and maintaining structural integrity after 30 s of burning. The structural–functional integration ensures efficient Na⁺ conduction (3.37 × 10⁻³ S cm⁻¹) and stable performance from − 20 to 60 °C.
