Mixtures, based on the N-butyl-N-methylpyrrolidinium bis(trifluoromethanesulfonyl)imide (PYR14TFSI) ionic liquid and the NaTFSI salt, as low flammability and volatility electrolytes for safer sodium electrochemical energy storage devices, were prepared and investigated in terms of thermal and ion-transport properties. The PYR14TFSI-NaTFSI electrolytes showed melting point down to - 30 C. No difference in terms of ion-transport properties was observed with respect to analogous lithium electrolyte systems. Conductivity values above 1 × 10- 3 S cm- 1 were observed at room temperature. © 2014 Elsevier B.V.

Abstract
Mixtures, based on the N-butyl-N-methylpyrrolidinium bis(trifluoromethanesulfonyl)imide (PYR14TFSI) ionic liquid and the NaTFSI salt, as low flammability and volatility electrolytes for safer sodium electrochemical energy storage devices, were prepared and investigated in terms of thermal and ion-transport properties. The PYR14TFSI-NaTFSI electrolytes showed melting point down to - 30 C. No difference in terms of ion-transport properties was observed with respect to analogous lithium electrolyte systems. Conductivity values above 1 × 10- 3 S cm- 1 were observed at room temperature. © 2014 Elsevier B.V.File in questo prodotto:
