ELECTROCHEMICAL-BEHAVIOR OF TIN OXIDE IN THE PRESENCE OF LITHIUM ION IN ACETONITRILE

We report an attempt to provide evidence for the doping-dedoping of li thium cations into an F--doped SnO2 transparent conductive substrate. The investigation was performed in anhydrous acetonitrile charged with alkaline salts containing Li+ ions: 0.1 M LiBF4 and 0.1 M LiSO3CF3. A fter polarization in a potential range sufficiently positive to ensure that Li deposition does not occur, the material was analyzed by scann ing electron microscopy and energy-dispersive X-ray analysis, and the chemical composition of the surface layers was determined by X-ray pho toelectron spectroscopy.
