Electrochemically lithiated V2O5 films: An optically passive ion storage for transparent electrochromic devices

  • A. Talledo (a1), A. M. Andersson (a1) and C. G. Granqvist (a1)


LiyV2O5 films were produced by reactive de magnetron sputtering followed by electrochemical posttreatment in LiClO4. X-ray diffraction showed an orthorhombic structure. Spectrophotometric transmittance and reflectance measurements demonstrated that the luminous and solar absorptance increased moderately when y increased from zero to unity. It is argued that LiyV2O5 is useful as an ion storage material operating in conjunction with electrochromic films.
