Outline of Final Research Achievements

The principal investigator attempted to explore efficient battery electrode materials where new organic molecules were published with their physical/chemical properties (RSC Adv. 2019, 9, 40031; RSC Adv. 2021, 2, 2263; JPP 2020, 24, 191; Org. Lett. 2020, 22, 4400).
Organic batteries with elongated π-conjugation molecules having interconversion capability between antiaromatic and aromatic conformations were investigated (Molecules 2019, 24, 2433). Also, high durable secondary organic batteries assembled with large composite (70%) NiNc electrodes and highly concentrated dual ion liquid provided high charge-discharge performances, enhanced working-life of batteries, fast charging rate, and high durability of organic electrodes (Mater. Adv. 2021, 2, 2263, front cover of the issue). Influential dual-ion mobilities of an ionic liquid through appropriate cavity spheres in electrodes furnished significantly improved battery performances were
established (Batter. Supercaps 2021, 4, 1605).
