Abstract The[Li1+xAlxTi2-x(PO4)3]solid electrolyte in lithium-air batteries was prepared by solid phase sintering method. The Li2CO3， AI2O3， TiO2， NH4H2PO4 were used as raw materials. The properties of the electrolyte were studied by changing the different[x]and sintering temperature. The structure and properties of the electrolyte were characterized by XRD， SEM and EIS. The results show that pure LATP is prepared when[x＝0.2.]The conductivity of LATP at the room temperature is 4.89×10－5 S/cm when the sintering process is sintering at 350 ℃ for 2 h， at 600 ℃ for 2 h and at 1 000 ℃ for 8 h.
