Abstract:

Binary phase diagrams of carbonates and esters were systematically measured, and the binary interaction parameters were thermodynamically and computationally evaluated. Based on these parameters, ternary and quaternary phase diagrams were reliably calculated and plotted for the carbonates and esters. The results showed that the freezing point of a solvent can be effectively lowered by adding the right solvent component in the right amount so that electrolytes as low-melting as 100 degrees C can be formulated. The effectiveness could be further enhanced by adding a component with properties similar to the host component whose freezing dominates that of the electrolyte.
