The surface layers formed on the lithium electrode under various conditions in different electrolytes, using 1,3-dioxolane or 2-methyltetrahydrofuran as solvent, and LiClO4, LiAsF6 or LiPF6 as solute, have been studied. The kinetic properties of the lithium electrode in presence of such surface layers were determined by electrode impedance spectroscopy leading to a clarification of the elementary conduction, transfer, and diffusion processes. An analysis of the characteristic parameters of the impedance diagrams, according to the theory of the frequency response of the binary electrolytes, revealed that the surface layers can have properties similar to those of liquid, solid, and/or polymer electrolytes.
