Abstract
Mg0.5Zr2(PO4)3 is a priority electrolyte for Mg solid state batteries. However, it is difficult to achieve high density and phase purity simultaneously, especially in thin films. Here, we processed liquid-feed flame spray pyrolysis synthesized MZPFex nanopowders to make transparent films via simple pressureless sintering at 1100°C. The influence of Fe on the phase and microstructure are discussed. In particular, dense and high phase purity Mg0.6Fe0.2Zr1.8(PO4)3 exhibits extremely low ionic area specific resistance, 1.6 kΩ cm2. This paper presents an effective method to prepare dense, high phase purity solid electrolytes at modest sintering temperatures.
