| Outline of Final Research Achievements |
This research is basic/applied research aiming to dramatically improve performance, durability and reliability by creating fuel cells and secondary batteries from ceramics and metals. The obstacle to the commercialization of solid state batteries is due to the fact that they are mainly composed of ceramic members with extremely low mechanical reliability. Therefore, in this research, we have succeeded in developing a battery that combines performance, durability, and reliability by combining some of the battery components with a metal having a nano-porous structure. In addition, we succeeded in developing the world's first non-destructive evaluation method that can quickly evaluate the stability of the interface structure.

| Academic Significance and Societal Importance of the Research Achievements |
全固体電池を創成する上で最も重要なことは新規な材料開発に加えて材料同士の組み合わせ方や構造最適化である．本研究では組み合わせる金属部材の構造をナノポーラス化することでセラミックスとの最適界面の創成に成功した．また，その界面の安定性を迅速に評価できる手法を開発した．本成果は全固体電池のみならず，様々な積層デバイスに応用できることが期待できる．
