Outline of Final Research Achievements

Composite materials consisting of a fast lithium ion conductor and a dielectric oxide were synthesized for the fundamental material applied to the capacitor with large capability. Firstly, the modification of the ionic radii of A site cations in perovskite structure effectively enhanced the lithium ion conductivity. Secondary, the 2- and 3-dementional composite materials consisting of lithium ion conductor and dielectrics were fabricated and evaluated. The expected large polarization with low dielectric loss wasn’t however obtained until now.
