Competition for development of advanced materials known as "ionic liquids" is now beginning all over the world. Ionic liquids are being called "the third liquid" as they are completely different from aqueous solutions or organic solvents, and yet are notable for having the same properties as solvents in not evaporating easily and conducting electricity. They are garnering attention for having functionality that is simply not possible with other liquids.
For example, using an ionic liquid for the electrolyte in a lithium-ion rechargeable battery improves safety and durability. Such a battery was even installed on a satellite, and succeeded in charging and discharging in space. Also, using ionic liquids to make biomass energy for renewable energy can reduce both time and cost compared to conventional methods. In the field of medical care, research is underway to reduce the burden on patients by using the properties of ionic liquids so that medicine can be absorbed through the skin. Ionic liquids have the potential to change our lives significantly.
