Abstract
The room temperature stability of the Li interface in the presence of 1,2-dimethyl-3-propylimidazolium imide and methide was followed by ele ctrochemical impedance spectroscopy for a period of 112 days. We found that while Li foil initially reacted with both ionic liquids, the int erfacial film on Li formed in the imide-based electrolyte stabilized a t an interfacial resistance of 1.5 k Ohm cm(2), while that for the met hide-based electrolyte rose to an interfacial resistance value exceedi ng 50 k Ohm cm(2).
