摘要：

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