Abstract : Developing high-performance solid electrolytes for sodium-ion battery architectures requires a fundamental understanding of how network modifiers regulate alkali-ion migration pathways. Here, we examine the structural and electrical properties of a series of sodium zinc phosphate glasses modified with systematically varied ZnO content (x = 0 to 5 mol%). Unlike multi-valent transition metal oxide glass systems, the glasses investigated here behave as purely ionic conductors. Complex impedance plane analyses, conducted over a broad temperature and frequency range, show that the introduction of ZnO alters the structural topology of the sodium phosphate matrix, giving rise to non-linear, compositiondependent changes in DC conductivity and activation energy. X-ray diffraction analysis confirms the fully amorphous, vitreous nature of the synthesized compositions, characterized by broad, diffuse scattering halos.

Keywords : Sodium Phosphate Glass; ZnO; Electrical Conductivity; Activation Energy; Mixed-Modifier Effect; Arrhenius Relation
