Tungsten Oxide Electrochromic Film Applied for Energy-efficient Glass

Tungsten oxide electrochromic film for producing energy-efficient glass is an electrochromic material with good cycle stability. According to experts, cycle stability is an important indicator of the industrialization of electrochromic devices. The experimental data shows that the cycle life of electrochromic devices must reach more than 100,000 times before they can be practically applied to large-scale production.

The experts also introduced that the cycle life of an electrochromic device mainly includes the cycle life of electrochromic film, the cycle life of electrolyte, and the intrinsic degradation of material. Wherein, the cycle life of electrochromic film mainly refers to the problem of the bonding force between the film and the substrate and the change of the film structure. The cycle life of electrolyte refers to the resistance of electrolyte to decomposition under the action of voltage when the external voltage is applied to the device. The intrinsic degradation mainly refers to the decline of optical properties caused by ions trapping inside material.
