Outline of Final Research Achievements

The all-solid-state lithium-ion batteries (ASS-LiBs) have garnered much attention as the next-generation secondary batteries owing to their high energy densities and high safety. It is important to establish the innovative production processes of ASS-LiBs for realization of a low-carbon society. This study focused on the liquid-phase synthesis of nanosized solid electrolytes and the liquid-phase coating of solid electrolytes on the active materials to elucidate the key physicochemical phenomena in each step.

Academic Significance and Societal Importance of the Research Achievements

全固体電池を実用化するには、素材が有する超イオン伝導体にさらに機能性を付与し、優れた複合材料を作成するプロセス技術の確立が必須である。本課題は、このプロセス構築に焦点を当て、化学工学・粉体工学の見地から切り込む世界初の取り組みである。得られる結果は全固体電池製造プロセスの研究開発を先導するもので、社会的波及効果も極めて大きい。
