Abstract

Li0.4La0.56TiO3 (LLTO) lithium-ion conducting solid electrolyte has been synthesized by aqueous sol-gel synthesis method. The free standing and alumina substrate supported thick films have been prepared from the obtained powder by tape casting. The films and bulk ceramics were studied by impedance spectroscopy in the frequency range from 10 Hz to 10 GHz. The equivalent circuit modelling was implemented in order to determine the electrical parameters of LLTO films and ceramics. The free standing LLTO films grain conductivity was found to be similar to the one of ceramic sample, while the grain boundary conductivity of the free standing film was slightly higher compared to LLTO ceramics.

LLTO厚膜的电学性能

采用水相溶胶-凝胶法合成了Li0.4La0.56TiO3 (LLTO)锂离子导电固体电解质。用胶带铸造法制备了独立的、氧化铝基板支撑的厚膜。采用阻抗谱法在10hz ~ 10ghz频率范围内对薄膜和体陶瓷进行了研究。为了确定LLTO薄膜和陶瓷的电学参数，对等效电路进行了建模。发现自由立LLTO薄膜的晶粒电导率与陶瓷样品相似，而自由立LLTO薄膜的晶界电导率略高于陶瓷样品。
