| Outline of Final Research Achievements |
We developed a sintering technique capable of forming a thin and dense crystal/glass composite at low temperature, using self-organized assembly structure arrangement of plate-shaped crystals. Concretely, the following were constructed: Growing of the solid electrolyte crystal of the plate shape using the topotactic reaction and integration technology of the masonry structure. As a result of the critical current density measurement, the labyrinth effect by the masonry integration was recognized. In addition, it was found that the ion conduction path which preferentially diffused the glass electrolyte layer was formed by covering the plate-like crystal surface with the solid electrolyte layer made of low melting point glass of which conductivity was higher. In addition, the new garnet type solid electrolyte which was excellent in ionic conductivity and phase stability in grain boundary and hetero-interface was developed.
