复合BaTiO3的Li0.5La0.5TiO3固体电解质的制备和性能
Preparation and properties of Lio.5Lao.5TiO3 mixed with BaTiO3
摘要
Abstract
A pure phase of the solid electrolyte Li0.5La0.5TiO3 (LLTO) was prepared by the conventional solid-state reaction method, and those LLTO powders were mixed with BaTiO3 nano particles to prepare the composite. The microstructure morphology and conductivity properties of the composite were investigated by X-ray diffraction,scanning electron microscope and AC impedance method. The grain conductivity of LLTO bulk sample is 1.1 x 10-3S/cm. The perovskite-type solid solution (Li,La,Ba)TiO3 rods can be found in the composite. At the lower dopant concentration (<10%), the grain conductivity of the composite electrolyte is higher than that of the pure LLTO. The grain conductivities of LLTO and LLTO doped with 5 % BaTiO3 at 120 ℃ are 0.84 x 10-2S/cm and 2.39 x 10-2 S/cm respectively.关键词
