Materials for high-performance electrochromic windows must fulfill various requirements, e.g., high optical contrast, fast response time, and stability. The construction and characterization of a device with technologically interesting properties are described. The device uses two active polymer electrode materials with complementary electrochromic behavior and a complex between a commercial elastomer and LiClO4 as the solid electrolyte. The cell can be assembled under atmospheric conditions and exhibits good contrast between the colored and bleached forms.
