Abstract
An aqueous electrolyte composition suitable for a lithium secondary battery is provided. The aqueous electrolyte composition contains water; lithium bis(fluorosulfonyl) imide (LiFSI); and an ionic liquid comprising an organic cation and a bis(fluorosulfonyl) imide anion (FSI); wherein the ionic liquid is a liquid at 20° C. A lithium secondary battery containing the aqueous electrolyte and a vehicle at least partially powered by the battery are also provided.
