Abstract We prepared and optimized the ionically conducting perovskite-type Li 0.33 La 0.56 TiO 3 by an adipic acid-assisted sol-gel process. A high ionic conductivity of 0.131 mS cm −1 was obtained at an ambient temperature by adjusting the synthesis temperature, holding time, and cooling process. A dramatic improvement in the Li 0.33 La 0.56 TiO 3 conductivity was noted in each step. Interestingly, a tetragonal-to-cubic structural transition was evident during the quenching process unlike in the conventional slow cooling process. An increase in the bottleneck site volume was observed that facilitated Li + ion migration for enhanced conductivity.

通过己二酸辅助溶液工艺定制钙钛矿 Li 0.33 La 0.56 TiO 3：一种有前途的锂电池固体电解质

摘要 我们通过己二酸辅助溶胶-凝胶法制备并优化了离子导电钙钛矿型Li 0.33 La 0.56 TiO 3 。通过调节合成温度、保持时间和冷却过程，在环境温度下获得了 0.131 mS cm -1 的高离子电导率。在每个步骤中都注意到 Li 0.33 La 0.56 TiO 3 电导率的显着改善。有趣的是，与传统的缓慢冷却过程不同，在淬火过程中，四方到立方的结构转变很明显。观察到瓶颈位点体积的增加促进了 Li + 离子迁移以提高电导率。
