Abstract
We have synthesized Li0.5−y Nay La0.5 Nb2 O6 and Li0.5−y Nay La0.5 Ta2 O6 defect perovskite solid solutions with 0 < y ≤ 0.5. Lithium ion diffusion in the investigated system exhibits no percolation effect. In the Li0.5−y Nay La0.5 Nb2 O6 system, the ionic conductivity as a function of sodium content has a maximum due to two competing factors: the increase in perovskite cell volume and the decrease in lithium ion concentration. The ionic conductivity of Li0.5−y Nay La0.5 Ta2 O6 samples decreases with sodium content.
