The need to reduce greenhouse gas emissions and guarantee a stable reliable energy supply has resulted in an increase the demand for sustainable storage solutions over last decade. Rechargeable batteries with solid-state electrolytes (SSE) have become focus area due their potential increased density, longer cycle life, safety conventional liquid electrolytic batteries. superionic sodium conductor (NASICON) Na3Zr2Si2PO12 gained lot of attention among ESS because its exceptional electrochemical properties, which make it promising candidate sodium-ion NASICON’s open frame structure makes possible transport ions efficiently even at room temperature, while wide window enables high-voltage operation reduces side reactions, resulting safer battery performance. Furthermore, NASICON is more compatible ion systems, can help electrode interface issues, simple process. characteristics highly desirable vital material aim this study prepare characterize ceramic membranes that contain Na3.06Zr2Si2PO12 Na3.18Zr2Si2PO12, measure stability seawater serve as solid electrolytes. surface analysis revealed powder specific 7.17 m2 g−1, than Na3.18Zr2Si2PO12 powder’s 6.61 g−1.
