Outline of Final Research Achievements

Li-ion conducting nanosheets were developed, and the ionic conducting properties were examined of the thin film composed of the Li-ion conducting nanosheets. Li-ion batteries with horizontally configured electrodes did not work for employing the high ionic conductivity of the thin film composed of the Li-ion conducting nanosheets, whereas Li-ion batteries with vertically configured electrode-electrolyte-electrode worked under room temperature. The capacity of these batteries were limited by large interfacial resistance between the electrodes and electrolyte composed of the Li-ion conducting nanosheets.
