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 degrees C. A conductivity close to 4 x 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. (C) 2014 Elsevier B.V.
