Lithium-Ion Conductive Film Membrane of Li 0.3La 0.57TiO 2 Perovskite Structure and its Application in Li-Air Batteries

Abstract

Impacts of precursor solution recipe, processing parameters, and pellet thickness on the lithium ionic conductivity of the ceramic materials with perovskite structure of Li 0.3La 0.57TiO 2 0.3La 0.57TiO 2 0.3La 0.57TiO 22 (i.e., TiO 2 sol) and then Li+ and La+ were added to the colloidal TiO 2 was on the order of 10-5 S/cm. It also showed that the temperatures corresponding to a full decomposition for Li 0.3La 0.57TiO 2 is about 750°C and materials start forming perovskite structure when temperature reaches about 900°C and the lithium ionic conductivity gains about 21% increase when the pellet thickness is reduced to about ¼.
