Abstract
Multi-layer electrochromic structures comprising an anodic electrochromic layer comprising a lithium nickel oxide composition on a first substrate, the anodic electrochromic layer comprising lithium, nickel and a Group 6 metal selected from molybdenum, tungsten and a combination thereof, wherein (i) the atomic ratio of lithium to the combined amount of nickel, molybdenum, and tungsten in the anodic electrochromic layer is at least 0.4:1, respectively, (ii) the atomic ratio of the combined amount of molybdenum and tungsten to the combined amount of nickel, molybdenum and tungsten in the anodic electrochromic layer is at least about 0.025:1, respectively, and (iii) the anodic electrochromic layer exhibits an interplanar distance (d-spacing) of at least 2.5 Å as measured by X-ray diffraction (XRD), comprises at least 0.05 wt. % carbon, and/or has a coloration efficiency absolute value of at least 19 cm2/C.
