Abstract

Multi-layer devices comprising a layer of an electrochromic lithium nickel oxide composition on a first substrate, the lithium nickel oxide composition comprising lithium, nickel and a Group 4 metal selected from titanium, zirconium, hafnium and a combination thereof.

Claims

exact text as granted — not AI-modified

What is claimed is: 
     
         1 . A multi-layer electrochromic structure comprising a first substrate and an anodic electrochromic layer comprising a lithium nickel oxide composition on the first substrate, the anodic electrochromic layer containing lithium, nickel, and at least one Group 4 metal selected from the group consisting of titanium, zirconium, and hafnium, wherein
 (i) the atomic ratio of lithium to the combined amount of nickel and such Group 4 metal(s) in the anodic electrochromic layer is at least 0.4:1, respectively, and   (ii) the anodic electrochromic layer exhibits an interplanar distance (d-spacing) of at least 2.5 Å as measured by X-ray diffraction (XRD).
