|Outline of Final Research Achievements
We focused on amorphization of sulfur-rich transition-metal sulfides for achieving high capacity and long cycle life. Amorphous TiS3 showed better charge-discharge performance than crystalline TiS3 in all-solid-state cells. Structural analyses for amorphous TiS3 revealed that the reaction mechanism during charge-discharge process was based on sulfide-anion redox with reversible structural changes. Amorphous sulfides including Mo, Fe, or V element were mechanochemically prepared and they exhibited high capacity and good cyclability.
