제목 Ionic Liquid as Electrolytes for Lithium ion Battery
초록 A series of imidazolium-based zwitterionic compounds having both a propylsulfonate group at 3-position and an ester group at 1 or 2-position were synthesized and their interactions with LiPF6 were investigated. FT-IR study and theoretical calculation using density functional theory showed that the interactions of the zwitterionic compound with LiPF6 varied significantly with the location of the ester group on the imidazolium ring. The electrochemical stability of the imidazolium-based zwitterionic compound was significantly improved by introducing an ester group at the C-2 position of the imidazolium ring.
