Preparation and characterization of NaI-Na3PO4 sodium ion conducting solid electrolyte with PLLTMEDA as an additive for sodium batteries / Noorazmi Hassan

New binary inorganic salt sodium iodide (NaI)–sodium phosphate (Na3PO4) prepared by mechanical milling for 3 hours and low sintering temperature method at 50 ºC exhibits maximum ionic conductivity of (1.02±0.19) × 10−4 S cm−1 at room temperature for the composition 0.50 NaI : 0.50 Na3PO4. The increa...
