Preparation and Characterization of Lithium Ion Conductive Membranes Constructed from Three-Dimensional Ordered Porous Material

Abstract

In order to create all solid-state rechargeable lithium battery with a high discharge capacity, a three-dimensional matrix consisting of solid electrolyte and active material has to be developed. In this study, we create Li0.35La0.55TiO3 ceramics with an inverse opal structure by colloidal templating method. Obtained polystyrene/Li-La-Ti-O gel composite was heated at 450°C and 1000 C. At 450°C, a desired three-dimensionally ordered macro-porous Li-La-Ti-O amorphous membrane was obtained. At 1000 °C, the obtained membrane had a perovskite structure.
