PROCESS FOR PREPARING A MULTI-LAYER ELECTROCHROMIC STRUCTURE
First Claim
1. A process for preparing a multi-layer device, the process comprising depositing a film of a liquid mixture comprising lithium, nickel, and at least one bleached state stabilizing element onto a surface of a substrate, and treating the deposited film to form a layer of a lithium nickel oxide composition on the substrate, the lithium nickel oxide composition comprising lithium, nickel and the bleached state stabilizing element(s) and being electrochromic, wherein(i) the atomic ratio of lithium to the combined amount of nickel and the bleached state stabilizing element(s) in the lithium nickel oxide composition is at least 0.4:
- 1, respectively,(ii) the atomic ratio of the combined amount of the bleached state stabilizing element(s) to the combined amount of nickel and the bleached state stabilizing elements in the lithium nickel oxide composition is about 0.025;
1 to about 0.8;
1, respectively, and(iii) the bleached state stabilizing element(s) in the lithium nickel oxide composition is/are selected from the group consisting of Y, Ti, Zr, Hf, V, Nb, Ta, Mo, W, B, Al, Ga, In, Si, Ge, Sn, P, Sb and combinations thereof.

Abstract
Process for preparing a multi-layer electrochromic structure comprising depositing a film of a liquid mixture onto a substrate and treating the deposited film to form an anodic electrochromic layer comprising a lithium nickel oxide composition, the anodic electrochromic layer comprising lithium, nickel and the bleached state stabilizing element(s) wherein in the film (i) the ratio of lithium to the combined amount of nickel and the bleached state stabilizing element(s) is at least 0.4:1, (ii) the ratio of the combined amount of the bleached state stabilizing element(s) to the combined amount of nickel and the bleached state stabilizing elements in the lithium nickel oxide composition is at least about 0.025:1, and (iii) the bleached state stabilizing element(s) is/are selected from the group consisting of Y, Ti, Zr, Hf, V, Nb, Ta, Mo, W, B, Al, Ga, In, Si, Ge, Sn, P, Sb and combinations thereof.
