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.

最终目标是最终开发所有固态锂离子电池。 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收藏家。通过这项研究，我建立了控制包含Li和Ru元素的化合物薄膜组成的方法，这些薄膜很容易由于蒸发或气体散射而丢失。所有获得的薄膜均显示单晶体体积等效性能：电荷/放电能力，离子电导率和电子电导率。
