Poly(vinyrlidenefluoide)-Hexafluoropropylene–Methyl N-methylpyrrolidinium-N-acetate Trifluoromethanesulfonylimide–Lithium Trifluoromethanesulfonylimide Gel Electrolytes |
| 초록 |
New polymer-ionic liquid-lithium salt gel electrolytes (PILGEs) were prepared using poly(vinylidene fluoride)-hexafluoropropylene copolymer (PVdF(HFP), methyl N-methylpyrrolidinium-N-acetate trifluoromethanesulfonimide ([MMEPyr][TFSI]), and lithium trifluoromethanesulfonylimide (LiTFSI) in order to investigate the effect of ionic liquids containing ester group on electrochemical properties of polymer gel electrolytes. The free standing ionic gels consisting of PVdF(HFP), [MMEPyr][TFSI], and LiTFSI were prepared in the range of mole ratio of polymer / [MMEPyr][TFSI] / LiTFSI = 1 / 2 / 0.1~1. Ionic conductivities for the prepared PILGEs were measured with increasing temperature and changing weight ratio of LiTFSI and the obtained values were reasonable (10-4 S•cm-1) over the operating temperatures. |
