ABSTRACT:
This invention provides a nonaqueous electrolyte battery that has excellent output characteristics, is small in individual difference, and is more stable. The nonaqueous electrolyte battery comprises a negative electrode and a positive electrode that contain or can occlude and release lithium, a lithium salt-containing ionic liquid and is characterized in that the electrolyte contains a cation containing a fluoroalkyl group attached through a methylene chain to a basic structure selected from the group consisting of imidazolium, piperidinium, and pyrrolidinium structures.
