Abstract
The structural features and electrophysical properties of lithium-conducting compounds having defect perovskite structure based on Li0.5La0.5Nb2O6 and Li0.5La0.5TiO3 were studied using X-ray diffraction and synchrotron analyses, potentiometry, and complex impedance spectroscopy. Intercalated lithium was found to differently influence ion conductance in titanium- and niobium-containing materials. This difference was found to arise from the structural features of the materials. The systems studied have high chemical diffusion coefficients of lithium (D +Li = 1 × 10−6 cm2/s for Li0.5La0.5Nb2O6 and D +Li = 3.3 × 10−7 cm2/s for Li0.5La0.5TiO3).
