V2O5 thin films were prepared by the sol-gel spin coating process.
The Li+ ions insertion effect on optical and electrochromic properties
of those films was studied. The diffusion coefficient was calculated using
both cyclic voltammograms and chronoamperometric curves. The amount x of
Li+ ions in Li
V2O5 was also calculated. Finally, the
electrochromic performance evolution characteristics such as the
reversibility, coloration efficiency, coloration memory stability and
response time were studied.
