Second Phase Effects on the Conductivity of Non-Aqueous Salt Solutions: “Soggy Sand Electrolytes”


  • We thank J. Fleig and H. Li for useful discussions. We also acknowledge the competent remarks from the reviewers.


Introducing insulating phases into non-aqueous salt solution leads to remarkable conductivity enhancements, an effect ascribed to breaking up of ion pairs. This new class of electrolytes combines the high ionic conductivities of liquids and beneficial mechanical properties of soft matter (“soggy sand”; see Figure).
