Outline of Final Research Achievements

Development of high-performance electrochemical energy storage devices is very important for sustainability purpose and low carbon society. We have investigated new solid-state electrochemical reactions using oxide-ion as a mobile carrier, which is applicable to alternative batteries to the state-of-the-art lithium-ion batteries. After exploration for many oxide compounds, we have found a novel oxide compound that exhibit reversible oxide-ion intercalation/deintercalation. Indeed, this compound work as an electrode materials in rechargeable batteries.
