| Research Abstract |
The final goal is to develop ultimately high-power all solid-state Li-ion batteries. In order to achieve this, I have succeeded in making epitaxial, orientation controlled LiCoO_2 thin films, which work as cathode active material, Li_<0.33>La_<0.56>TiO_3 thin films, which work as air-stable highly ion conducting oxide solid electrolyte, and SrRuO_3, Sr_2RuO_4, and Sr_3Ru_2O_7 thin films, which work as current collector. Through this study, I have established the way to control the composition of compound thin films containing Li and Ru elements, which are easily lost due to evaporation or gas scattering. All obtained thin films show single crystal bulk equivalent electric properties: charge/discharge capacity, ionic conductivity, and electronic conductivity, respectively.
