Solid solutions with defect perovskite structure have been obtained in the systems Li0,5-уNayLa0,5TiO3, Li0.5-yNayLa0.5◊Nb2O6 and Li0.5-yNayLa0.5◊Та2O6 at 0 ≤ y ≤ 0.5. Their structure has been shown to undergo partial disordering with increasing sodium content in the system Li0.5-yNayLa0.5◊Nb2O6 as in the system Li0.5-yNayLa0.5◊Та2O6 structure has been ordering. Lithium diffusion in system Li0,5-уNayLa0,5TiO3 follows a percolation model for the lithium diffusion. The ionic conductivity as a function of sodium content in the system Li0.5-yNayLa0.5◊Nb2O6 has a maximum. The ionic conductivity of Li0.5-yNayLa0.5◊Ta2O6 samples decreases with sodium content.

AbstractThe search for lithium ion conductors in crystalline or polycrystalline solid state ionic materials has resulted in finding a new class of compounds. Five new, stable, homogeneous compounds formed in the lithium alcohol systems, LiI—(ROH)x for R=CH3CH2OH, CH3CH2CH2OH, CH3CHOHCH3,, and CH3OH have been identified and characterized.
