Paper Title:
Ionic Liquid Binary Mixtures for Low Temperature Applications
  Abstract

The thermal and transport properties of PYR1(2O1)TFSI-PYR13FSI ionic liquid binary mixtures as electrolytes for low temperature electrochemical devices are reported in the present paper. The DSC measurements are in good agreement with the conductivity results. It is shown that the incorporation of even small mole fractions (x  0.3) of PYR1(2O1)TFSI into PYR13FSI strongly hinders the ability of the samples to crystallize. This results in a very large conductivity enhancement for the PYR1(2O1)TFSI-PYR13FSI binary mixtures, particularly at low temperatures, that were seen to approach conduction values of 10-4 Scm-1 and 10-3 Scm-1 at -40°C and -20°C, respectively. Such an interesting behavior makes PYR1(2O1)TFSI-PYR13FSI binary mixtures particularly appealing for low temperature applications.
