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.
