Abstract

The effect of Pt co-sputtering on the characteristics of amorphous V ₂O₅ films, grown by dc reactive sputtering, was investigated using glancing angle x-ray diffraction (GXRD), transmission electron microscopy (TEM), transmission electron diffraction (TED) and charge-discharge measurement. It was found that the Pt co-sputtering processes influence the growth mechanism as well as the characteristics of V ₂O₅ films. In addition, it was found that the Pt co-sputtered V₂O₅ cathode film exhibits cyclibility better than the undoped V₂O₅ cathode film, due to the absence of short range order, which is generally shown in undoped V₂O ₅ cathode films. Possible explanations for the cycling behavior of the Pt doped V₂O₅ cathode film and Pt co-sputtering effect on the electrochemical properties of thin film batteries are suggested.
