| Outline of Final Research Achievements |
In this work, for the first time we developed a new ionic liquid monomer of acyl sulfonamide producing ionic-liquid type anionic polymer by radical polymerization. Anionic polymer type solid electrolyte is expected to attribute an improvement of the performance thanks to the weak static interaction between Li ion and the counter ion, and the immobilized anions therefore might lead to a favored cationic charge transport. An ionic-liquid type anionic polymer exhibited higher ionic conductivity than that of cationic polymers. Then the ionic-liquid type anionic polymer maintained high conductivity at ambient temperature because ionic liquid structure prevented glass transition.
Furthermore, an effect of promoting proton conduction was found in solid electrolyte in which the ionic liquid-type polymer brush-modified particles are three-dimensionally self-assembled, forming a continuous ion-conductive channel.
