| 英文摘要 | In this paper, the stability in humid air of Li_5La_3Ta_2O_(12) lithium ionic conductors synthesized by conventional solid-state reaction was investigated by internal friction, conductivity, weight variation, X-ray diffraction, and thermogravimetric analysis methods. It was found that when the Li_5La_3Ta_2O_(12) samples were aged in open air at room temperature, the internal friction peaks associated with the short-distance diffusion of lithium vacancies gradually shift toward higher temperature and increase in height, while the weight of the sample increases and impurity phases of LiOH H_20 appear. These results reveal that the Li_5La_3Ta_2O_(12) compounds are unstable against moisture in open air at room temperature. It was suggested that the protons from the moisture substitute the lithium ions in Li_5La_3Ta_2O_(12) samples to form Li_2O and new protonic derivatives, Li_(5-x)La_3Ta_2O_(12-x)(OH)_x (0 |
