摘要：

NASICON-type electrolyte Li1.4Al0.4Ti1.6(PO4)(3) attracts great attention with its high grain conductivity and stable microstructure. In this work, the Li1.4Al0.4Ti(1.6-x)Zrx(PO4)(3) solid-state electrolytes were synthetized. And the influences of ZrO2 addition on microstructural evaluation and ionic conductivity of Li1.4Al0.4Ti(1.6-x)Zrx(PO4)(3) were studied using powder X-ray diffraction, scanning electron microscopy and impedance spectroscopy. All synthetic samples adopted single phase LiTi2(PO4)(3) with NASICON type structure. The highest ionic conductivity of 0.54 mS/cm and the minimum activation energy of 0.232 eV were achieved for x = 0.04 sample sintered at 850 degrees C. These results indicate that ZrO2 added Li1.4Al0.4Ti1.6(PO4)(3) ceramic has a potential application in solid electrolytes.
