N2 - Li electrodes were freshly prepared in a variety of alkyl carbonate solutions, including DMC, EC-DMC and EC-DEC mixtures, containing LiAsF6, LiPF6 and LiBF4 as the salts, and H2O, HF and tributylamine as the contaminants/additives. The solutions' resistance, measured by impedance spectroscopy, changes systematically during contact with the Li electrodes (at open circuit potential), as a function of the solution composition and the salt, additives and solvent ratio. These changes in the solutions' resistance are discussed in light of the complicated surface chemistry of the Li electrodes in the solutions, which slightly affect the content of the conducting species in solutions.
