| Outline of Final Research Achievements |
I established an technique to analyze ionic conduction based on the graph theory in mathematics. The technique enables to analyze arrangement of ions even in a complicated crystal and and to find ionic conduction mechanism automatically by a computer. This contributes to development of solid electrolytes for advanced batteries.
I applied it to actual superionic conductors, and confirmed the usefulness. I presented the results to a domestic society, an international conference, and an academic paper. I exhibited the program code as an open source software.
