Abstract

Mg_0.5Zr₂(PO₄)₃ is a promising electrolyte for Mg solid-state batteries. But it is difficult to achieve high-density thin films with phase purity. Here, we synthesized Mg_0.5(1+ _x ₎Fe_xZr₂₋ _x(PO₄)₃ nanopowders using liquid-feed flame spray pyrolysis and used the product to form transparent thin films via simple pressureless sintering at 1100 °C. The influence of Fe on the phase and microstructure were discussed and the bottlenecks during Mg²⁺ conduction pathway were calculated. The dense and high-purity Mg_0.6Fe_0.2Zr_1.8(PO₄)₃ exhibited an extremely low ionic area specific resistance of 1.6 kΩ cm² at 200 °C. This paper presents a method for preparing dense, high-purity solid electrolytes at modest sintering temperatures.
