Ionic Conductivity and Composition of La/Li-TiO₂ amorphous spheres prepared with various ion exchenge conditions.

Abstract

/La/Li-TiO₂ amorphous spheres have synthesized by sol-gel and ion-exchenge method and resulted in single-phase (La, Li)TiO₃ lithium ionic conductor. Precise control of La/Ti and Li/Ti compositions was further required in order to acquire higher ionic conduction. The effects of La³⁺/Li⁺ ion exchange conditions on Li/Ti ratio of La/Li-TiO₂ amorphous spheres was then examined using various ethanol/water solutions. The Li/Ti ratio was increased with an increase in ethanol/water ratio in solutions for La³⁺/Li⁺ ion exchange and independent of La/Ti.
