Abstract
The solid electrolyte Li0.5La0.5TiO3 (LLTO) with high lithium ion conductivity was prepared by the conventional solid-state reaction method, and those LLTO powders were mixed with inactive second phase (Al2O3, MgO, SiO2) to give composites. The microstructure and conductivity properties of the composite are investigated by using X-ray diffraction, scanning electron microscope and AC impedance method. Those prepared LLTO is cubic crystal with superstructure. All conductivities of LLTO-based composites decrease with the addition of Al2O3 or MgO, but the grain boundary conductivity increases with the addition of SiO2.
