Tungsten oxide electrochromic film can be assembled into an electrochromic device such as an energy-saving glass by insulating glass packaging method. In this regard, some experts have taken out the picture of the large area electrochromic device assembled with tungsten oxide electrochromic film by insulating glass packaging, as shown in the following figure. So, how to use hollow glass packaging method to obtain a tungsten oxide electrochromic device?

Assembly of Tungsten Oxide Electrochromic Device by Hollow Glass Packaging Method
Step One: Attach an aluminum frame around a clean FTO conductive glass, seal it with butyl rubber, make the glass and aluminum frame fit well, then take a piece of FTO conductive glass coated with tungsten oxide film and attach it to the other side of the aluminum frame. And the gap is blocked with butyl rubber.
Step Two: the two pieces of glass are sealed with butyl rubber, so that the hollow part between the two glasses is completely isolated from the outside.
Step Three: Inject the prepared electrolyte into the hollow portion and assembling into a complete electrochromic device.
