An innovative electrolyte mixture, based on the novel N-butyl-N- ethylpyrrolidinium bis(fluoromethanesulfonyl)imide (PYR24FSI) ionic liquid and the LiFSI lithium salt, was prepared and its thermal and ion-transport properties were investigated. The FSI-based mixture showed fast crystallization kinetics with melting point around - 40 C. A conductivity close to 4 � 10- 3 S cm- 1 was reached at room temperature. This PYR24FSI-LiFSI mixture family has been found to be an appealing electrolyte for high safety and performance lithium battery systems. � 2014 Elsevier B.V.

Abstract
An innovative electrolyte mixture, based on the novel N-butyl-N- ethylpyrrolidinium bis(fluoromethanesulfonyl)imide (PYR24FSI) ionic liquid and the LiFSI lithium salt, was prepared and its thermal and ion-transport properties were investigated. The FSI-based mixture showed fast crystallization kinetics with melting point around - 40 C. A conductivity close to 4 � 10- 3 S cm- 1 was reached at room temperature. This PYR24FSI-LiFSI mixture family has been found to be an appealing electrolyte for high safety and performance lithium battery systems. � 2014 Elsevier B.V.File in questo prodotto:
