Beschreibung
Zusammenfassung:	The present invention provides ionic liquid that has bisfluorosulfonylimide anions as anions and one kind selected from the group consisting of imidazolium, pyrrolidinium, ammonium, and piperidinium cations as cations, is thermally and electrochemically stable, contains 10 ppm or less of halides, and has low viscosity and high electrical conductivity. The ionic liquid according to the present invention can be used as electrolyte in lithium secondary batteries, electrochemical devices, ultracapacitors, light-emitting battery cells, etc.
