Application

1-Butyl-1-methylpyrrolidinium tetrafluoroborate, a green solvent, is an ionic liquid that can be used in the formation of an electrolytic solution. An electrolytic solution can be used in a variety of applications such as double-layered capacitors, polymeric batteries, and solid-state actuators.
Ionic liquids (ILs) are molten salts with melting points lower than 100 °C. They usually consist of pair of organic cation and anion. ILs exhibit unique properties such as nonvolatility, high thermal stability, and high ionic conductivity and find applications as electrolytes in lithium/sodium ion batteries and dye-sensitized solar cells. They are also used as media for synthesis of conducting polymers and intercalation electrode materials.
