摘要

我们合成了Li0.5−yNayLa0.5 Nb2O6和Li0.5−yNayLa0.5 Ta2O6缺陷钙钛矿固溶体，浓度为0 <Y≤0.5。锂离子在研究体系中的扩散不表现出渗透效应。在Li0.5−yNayLa0.5 Nb2O6体系中，由于钙钛矿电池体积的增加和锂离子浓度的降低这两个相互竞争的因素，离子电导率随钠含量的变化最大。Li0.5−yNayLa0.5 Ta2O6样品的离子电导率随钠含量的增加而降低。

The structure and ionic conductivity of Li0.5−yNayLa0.5 {Nb,Ta}2O6 system

We have synthesized Li0.5−yNayLa0.5 Nb2O6 and Li0.5−yNayLa0.5 Ta2O6 defect perovskite solid solutions with 0 < y ≤ 0.5. Lithium ion diffusion in the investigated system exhibits no percolation effect. In the Li0.5−yNayLa0.5 Nb2O6 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−yNayLa0.5 Ta2O6 samples decreases with sodium content.
