| Research Abstract |
Quasi-solid-state composite electrolytes consisting of room temperature ionic liquids and oxide nanoparticles were synthesized for use as electrolytes of all-solid-state lithium rechargeable batteries. Attributed to the strong interaction between them, high concentration of room temperature ionic liquids could be confined at the oxide surfaces without remarkable loss of ion-transport properties regardless of the solid-like appearance. When the lower viscous room temperature ionic liquids are confined, the lithium ion transport is slown. On the other hand, the oxide surface contributes to the enhancement of the lithium-ion transport compared to the bulk when the higher viscous ones are confined. The all-solid-state lithium rechargeable battery using the quasi-solid-state electrolyte showed the noticeable charge - discharge performances.
