The electrochemical behaviour of 1,3-dioxolane—LiClO4 solutions—I. Uncontaminated solutions

The electrochemical behavior of 1,3-dioxolane (DN)—LiClO4 solutions with lithium and noble metal (eg gold, platinum) electrodes was investigated using surface sensitive FT-ir, scanning electron microscopy (SEM), X-ray microanalysis and electrochemical techniques. It was found that the salt and the solvent react with lithium or noble metal electrodes at low potentials to form surface films which control the electrochemical behavior of these systems. Their structure and mechanism of formation, as well as correlation between surface chemistry, surface morphology, and cycling efficiency of lithium electrodes in these solutions are discussed in detail.
