【 摘 要 】

A NASICON-type structured solid electrolyte of precursor for Li1.3Al0.5Ti1.3Nb0.2(PO4)3with high lithium-ion conductivity was prepared with solid-state reaction. Two samples have same structures without impurity phases. The highest total electrical conductivities of sintered pellets made with two methods of press method and tape casting calculated at 25°C were 4.65×10-4S/cm and 7.1×10-4S/cm, respectively. The conductivity of sample synthesized with tape casting is significantly increased, but relative density is 90% which is lower than relative density of 96% for sintered pellets synthesized with press method.
