Beschreibung
Zusammenfassung:	The present invention provides an ionic liquid useful for a lithium secondary battery, which is excellent in performance as an electrolyte material, such that the liquid has ionic conductance and a wide potential window, and is excellent in safety, as well as an electrolyte using the same. The present invention relates to an ionic liquid including a cyanophosphate-based anion represented by the following general formula (1), and an electrolyte using the same, a lithium secondary battery, and a process for producing the ionic liquid. [Chem 1] −P(CN)nX6-n (1) (Wherein X is a halogen atom and n is an integer of 1 to 6.)
