Tungsten Oxide Applied for Complementary Electrochromic Glass

Tungsten oxide may be applied for producing complementary electrochromic glass. As you may have known, tungsten trioxide is a well-developed electrochromic material with excellent electrochromic properties and a large light modulation range. It is a cathode coloring material. And nickel oxide is also a typical electrochromic material belonging to the anode coloring material. Therefore, a complementary electrochromic glass can be assembled with a tungsten oxide electrochromic film and a nickel oxide electrochromic film, as cathode coloring material and anode coloring material, respectively. And there are many researches on electrochromic devices based on tungsten trioxide and nickel oxide.

While experts say that there are still some problems with electrochromic technology, such as limited color change, slow transition speed, low cycle stability and immature assembly processes. So, the electrochromic devices have high requirements for electrochromic materials. And the safety of electrochromic devices and the study of leakage of liquid electrolytes have also been put on the agenda. Also, research on electrochromic device packaging is increasing.
