摘要：
Mg0.5Zr2(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)FexZr2-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 degrees 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 Mg0.6Fe0.2Zr1.8(PO4)(3) exhibited an extremely low ionic area specific resistance of 1.6 k Omega cm(2) at 200 degrees C. This paper presents a method for preparing dense, high-purity solid electrolytes at modest sintering temperatures.
