摘要： Solid, or highly viscous, organic electrolytes consisting of alkylimidazolium cation with alkyl, PEGylated and fluorinated side chains of different molecular weights were synthesized and characterized (cf. chemical structures in Schemes 1 and 2). The PEGylated/fluorinated imidazolium iodide is a solid organic electrolyte that has a conductivity of about 2×10−5 S/cm at 30° C. The ionic conductivity could be significantly increased (1.11×10−4 S/cm at 30° C. and S/cm at 2.88×10−3 at 90° C.) by blending the PEGylated/fluorinated imidazolium iodide with another solid electrolyte, 1-ethyl-3-methylimidazolium iodide (EtMImI). The PEGylated imidazolium iodides synthesized in the present work have conductivities in the range 1.6×10−4 S/cm to 2×10−4 S/cm at 30° C. and viscosities in the range 620 cP to 720 cP at 30° C. The iodide counter ion in the present electrolytes supplies the anion for the I−/I3− redox mediators for DSSCs. Therefore, the organic electrolytes of the present invention can be used even without the addition of inorganic salts such as LiI or KI. We found that the addition of an organic solid electrolyte, EtMImI, resulted in an increase in the ionic conductivity of the PEGylated/fluorinated imidazolium iodides, whereas the addition of the inorganic LiI led to a decrease in ionic conductivity. All the electrolytes are thermally stable until high temperatures (250° C. to 300° C.).

The PEGylated imidazolium iodides synthesized in the present work have conductivities in the range 1.6×10−4 S/cm to 2×10−4 S/cm at 30° C. and viscosities in the range 620 cP to 720 cP at 30° C. The iodide counter ion in the present electrolytes supplies the anion for the I−/I3− redox mediators for DSSCs.

摘要翻译：合成并表征了具有烷基咪唑鎓阳离子与不同分子量的烷基，聚乙二醇化和氟化侧链的固体或高粘度有机电解质（参见方案1和2中的化学结构）。 PEG化/氟化碘化咪唑碘化物是在30℃下具有约2×10-5S / cm的电导率的固体有机电解质。离子电导率可以显着增加（在30℃为1.11×10 -4 S / cm 和在90℃下2.88×10-3的S / cm），通过将聚乙二醇化/氟化咪唑鎓碘化物与另一种固体电解质，1-乙基-3-甲基咪唑碘化物（EtMlml）共混。在本工作中合成的聚乙二醇化咪唑鎓碘化物在30℃下的电导率范围为1.6×10 -4 S / cm至2×10 -4 S / cm，在30℃下的粘度范围为620cP至720cP 本电解液中的碘化物反离子为DSSC的I / I3-氧化还原介质供给阴离子。因此，即使不加入无机盐如Lil或KI，也可以使用本发明的有机电解质。我们发现添加有机固体电解质。 EtMlml导致聚乙二醇化/氟化咪唑鎓碘化物的离子电导率增加，而无机Lil的添加导致离子电导率的降低。所有的电解质都是热稳定的，直到高温（250〜300℃）。
