Outline of Final Research Achievements

In this research project, development of novel sodium-containing metal sulfide-based electrode active materials was aimed.
In the search for materials of Na-Ti-S system, four kinds of phases of amorphous phase, cubic rock salt type structure, layered Na2TiS3 having O-type structure and Na2TiS3 having P-type structure were found in the Na2TiS3 composition. In the search for Na-Fe-S-based materials, Na2FeS2 was found to be useful as an electrode active material with reversible charge and discharge for sodium ion batteries.
The structural analysis of each, the evaluation of the charge and discharge characteristics, and the elucidation of the charge and discharge mechanism were conducted.

Academic Significance and Societal Importance of the Research Achievements

ナトリウム-硫黄電池は、資源量が豊富なナトリウムと硫黄から構成される実用大型蓄電システムであるが、300°Cを超える高温作動が必要であるためエネルギー効率が悪く、溶融状態のナトリウムを用いるため安全面に不安がある。常温作動や安全性向上が可能になればより使いやすい大型電池が実現する。
本研究では、ナトリウムイオン電池用の電極活物質を創製した。4種類のNa2TiS3の作り分けに成功し、今後、多くの新物質を創製できることを示した。高温相Na2TiS3は1000サイクルでほぼ無劣化であった。Na2FeS2など安価な高容量電極活物質の開発し、ナトリウム電池用の硫化物系電極材料の研究の進展に貢献した。
