AbstractLithium garnet-type oxides Li7−2xLa3Zr2−xMoxO12(x=0, 0.1, 0.2, 0.3) ceramics were prepared by a sol-gel method. The influence of molybdenum on the structure, microstructure and conductivity of Li7La3Zr2O12were investigated by X-ray diffraction, scanning electron microscopy, and impedance spectroscopy. The cubic phase Li7La3Zr2O12has been stabilized by partial substitution of Mo for Zr at low temperature. The introduction of Mo (x≥0.1) can accelerate densification. Li6.6La3Zr1.8Mo0.2O12sintered at lower temperature 1100°C for 3 hours exhibits highest total ionic conductivity of 5.09 × 10−4 S/cm. Results indicate that the Mo doping LLZO synthesized by sol-gel method effectively lowers its sintering temperature and improves the ionic conductivity. © 2017 The American Ceramic Society
