Abstract
Fluorinated ionic liquids have been prepared to be used as catholytes in lithium battery cells. Such ionic liquids are immiscible with polyethylene-oxide-based solid polymer electrolytes, which may be used as separators in such cells. Such catholytes can increase the lifetime and boost the performance of lithium battery cells.
