摘要：
NASICON-type lithium-ion conducting solid electrolyte for Li1+xAlxGe0.2Ti1.8-x(PO4)(3) were prepared with solid-state method at 900 degrees C for 7 h. In this paper, we have studied the property of Li1+xAlxGe0.2Ti1.8-x(PO4)(3) solid electrolyte systems with various numbers of Al replaced Ti. The highest total electrical conductivity of the sintered pellets for Li1.45Al0.45Ge0.2Ti1.35(PO4)(3) at 25 degrees C was 1.0 x 10(-3) S/cm, which has NASICON-type crystalline structure without impurity phase. And the sintered pellet as x=0.45 in Li1+xAlxGe0.2Ti1.8-x(PO4)(3) systems also has highest relative density of 95.6% and highest three-point strength of 90 N mm(-2), respectively.
