Abstract :
Series of Li1.5Al0.5Ge1.5(PO4)3 glass ceramic samples were prepared in this work through the change of heat treatment temperature from 650 to 1050 °C. The structures of glass ceramic samples were characterized by means of high temperature X-ray diffraction and Field Emission Scanning Electron Microscope. And the lithium ionic conductivity was analyzed through AC impedance spectroscopy. Through heat treatment at 850 °C for 4 h for the base glass sample, we obtained a maximum conductivity of 5.8 × 10− 4 S/cm at room temperature.
