项目摘要
Recent research showed that supercapacitors based on electrochemically stable Ionic Liquid electrolytes are superior lo many conventional solvent based materials.With this project we want to apply a novel anion type, the fluorinated alkoxyaluminates [A1(0RF)4]- (especially RF = C(H)(CF3)2 and C(CF3)3), that was used in the past primarily as weakly coordinating anion (WCA) to prepare stable salts of chemically very reactive cations, as electrolytes for electrical double-layer capacitors (EDLC). Several of salts of the [A1(0RF')4]- family of WCAs form room temperature Ionic Liquids with low viscosity and high conductivity. Moreover, these WCAs are electrochemically very stable (e.g. up to +5.5 V vs. Li/Li+).These features point to a great potential of these also moderately priced WCAs to act as favourable electrolytes for EDLC devices. Also the size of the WCAs may be changed by varying RF and thus the effect of pore sizes in the solid electrodes may also be investigated in detail. During the project, three subsequent generations of [Al(ORF )4]- electrolytes shall be developed and fully tested in EDLCs. After each generation a careful assessment of the performance of the EDLC devices shall be done and results should be correlated with physical properties of the used WCA electrolytes as well as the electrode materials. An understanding of the reasons for failure or success of the WCA electrolytes shall be supported by quantum chemical calculations of relevant properties.
最近的研究表明,基于电化学稳定的离子液体电解质的超级电容器优于许多传统的溶剂型材料。在这个项目中,我们想要应用一种新型的阴离子类型--氟代烷氧基铝酸盐[A1(0Rf)4]-(特别是Rf=C(H)(CF3)2和C(CF3)3),过去主要作为弱配位阴离子(WCA)来制备化学性质非常活泼的阳离子的稳定盐,作为双电层电容器(EDLC)的电解液。[Al(0Rf‘)4]-系列WCA的几种盐形成了具有低粘度和高导电性的室温离子液体。此外,这些WCA在电化学上非常稳定(例如,高达+5.5V对Li/Li+)。这些特征表明,这些价格适中的WCA作为EDLC器件的有利电解液具有巨大的潜力。此外,WCA的大小可以通过改变RF来改变,因此也可以详细地研究固体电极中的孔大小的影响。在该项目期间,将开发三代后续的[Al(ORF)4]-电解液,并在EDLC中进行全面测试。在每一代之后,应仔细评估EDLC器件的性能,评估结果应与使用的WCA电解液和电极材料的物理性能相关联。对WCA电解液失败或成功原因的理解应通过相关性质的量子化学计算来支持。
