摘 要：Li1.3Al0.3Ti1.7（PO4）3 pellets sintered with different mole fractions of LiBO2 were prepared by sol-gel method.The structural identification,surface morphology,ionic conductivity,and activation energy of the pellets were studied by X-ray diffraction,scanning electron microscopy,and electrochemical impedance spectroscopy.The results show that all the Li1.3Al0.3Ti1.7（PO4）3 pellets sintered with different mole fractions of LiBO2 have similar X-ray diffraction patterns.The sintered pellet becomes denser and the boundary and corner of the particles become illegible with the increase of LiBO2.Among the Li1.3Al0.3Ti1.7（PO3）4 pellets sintered with different mole fractions of LiBO2,the one sintered with 1 mol% LiBO2 shows the highest ionic conductivity of 3.95×10-4 S.cm-1 and the lowest activation energy of 0.2469 eV.
