Figure 1: Temperature-dependent viscosity of IL-mixtures.
One of the main disadvantages of ILs - their high viscosity - can be overcome by using mixtures (Figure 1). In this talk we will present our latest results and developments in the field of ionic liquid based electrolytes for batteries and supercapacitors. In the latter cycling stability over 8 000 000 cycles has been achieved. The use of mixtures of ionic liquids and suitable additives in order to enhance performance and safety of zinc - air, aluminum - air and silicon - air batteries will also be discussed.
