Abstract

Vinyl group-substituted room-temperature ionic liquids (RTILs) were used for aiming at fabrication of high-safety batteries. The imidazolium-based ionic liquids used in this study had a vinylmetylene group and another alkyl group on an imidazolium cation. The charge-discharge profiles of batteries composed of a LiCoO2 cathode were compared between the different RTILs to know the factors of RTIL influencing the battery performances. The charge/discharge efficiency of a graphite anode was also investigated for total evaluation of the battery performances.
