Outline of Final Research Achievements

This research tried to improve film quality of LiBH4, which is a solid electrolyte having a good affinity with a Li metal anode. Since the Li metal anode has high Li capacity, LiBH4 may play a key role for future development of the all-solid-state batteries. The primary achievement of this research was successful establishment of growth method of high quality LiBH4 films with high purity and excellent flatness. In addition, this research could grow LiCoO2 and LiI films in preparation to fabrication of the all-solid-state batteries with a LiBH4 film as an electrolyte.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果により、電解質と電極の接合部で起こる化学現象を、薄膜技術を使用することでこれまでより深く理解することが可能になった。また、IoT情報ネットワークの普及に必須の自立型センサの電源と期待される薄膜型全固体電池の開発へ向けて前進した。
