Oxide films deposited by reactive radio frequency sputtering of target made of mixed CeO2and V2O5(1:1) powders show an anodic electrochromic character upon lithium insertion. As-deposited films look yellowish and become fully transparent for an inserted charge of 30 mC/cm2of Li ions. A total charge of 60 mC/cm2has been reversible cycled in the 1 to 5 V versus Li range in an electrochemical cell without any significant degradation. Following these preliminary results, films of Ce-V mixed oxide made by r.f. sputtering are suitable for working in tandem with tungsten oxide in a practical electrochromic device.
