以聚偏氟乙烯-六氟丙烯共聚物(PVDF(HFP))、甲基N-甲基吡咯烷-N-乙酸三氟甲磺酰亚胺([MMEPYR][TFSI])和三氟甲基磺酰亚胺锂(LiTFSI)为原料，制备了新型聚合物-离子液体-锂盐凝胶电解质(PILGE)，考察了含酯基离子液体对聚合物凝胶电解质电化学性能的影响。在聚合物/[MMEPYR][TFSI]/LiTFSI=1/2/0.1Scm∼1的质量比范围内制备了由聚偏氟乙烯(HFP)、[MMEPYR][TFSI]和LiTFSI组成的自由基离子凝胶。通过改变温度和LiTFSI的质量比，测量了所制备的PILGE的离子电导率，得到了在操作温度范围内的合理数值(10−4Scm−1)。
New polymer-ionic liquid-lithium salt gel electrolytes (PILGEs) were prepared using poly(vinylidenefluoride)-hexafluoropropylene copolymer (PVdF(HFP)), methyl N-methylpyrrolidinium-N-acetate trifluoromethanesulfonimide ([MMEPyr][TFSI]), and lithium trifluoromethanesulfonylimide (LiTFSI) in order to investigate the effects of ionic liquids containing an ester group on the electrochemical properties of polymer gel electrolytes. Free standing ionic gels consisting of PVdF(HFP), [MMEPyr][TFSI], and LiTFSI were prepared in a range of weight ratio of polymer/[MMEPyr][TFSI]/LiTFSI=1/2/0.1∼1. Ionic conductivities for the prepared PILGEs were measured with changing temperature and weight ratio of LiTFSI and the obtained values were found to be reasonable (10−4Scm−1) over the operating temperatures.
