Outline of Final Research Achievements

Development of electrode active materials with high capacity and reversibility is required to realize sodium secondary batteries. In this research project, we worked on establishing an academic foundation for sodium-containing metal sulfide electrode active materials, with the main objective of developing new sodium-containing metal sulfide materials and clarifying their physical properties as electrode active materials. Unlike the conventional concept of transition metal redox, this research aimed to develop a large charge-discharge capacity through redox by the entire metal sulfide constituent. In this study, we focused on iron, nickel, and molybdenum.

Academic Significance and Societal Importance of the Research Achievements

「ナトリウム含有硫化物合成」に関する研究基盤が確立できた。得られた成果は、硫化物系全固体ナトリウム二次電池の長年の課題である材料の量産性の課題の解決へのブレイクスルーとなり、資源量が豊富で量産性に優れる全固体電池の実現に大きく貢献することができる。
リチウムイオン電池やNAS電池は、日本で初めて実用化された電池である。本成果により、世界に先駆けた日本での全固体ナトリウム電池の実用化ができれば、産業界へのインパクトは極めて大きい。
