Abstract
Process for forming a multi-layer electrochromic structure, the process comprising depositing a film of a liquid mixture onto a surface of a substrate, and treating the deposited film to form an anodic electrochromic layer, the liquid mixture comprising a continuous phase and a dispersed phase, the dispersed phase comprising metal oxide particles, metal hydroxide particles, metal alkoxide particles, metal alkoxide oligomers, gels or particles, or a combination thereof having a number average size of at least 5 nm.
Claims24
A process for preparing a multi-layer electrochromic structure, 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 an anodic electrochromic layer comprising a lithiated nickel oxide, wherein
- (i) the atomic ratio of lithium to the combined amount of nickel and the bleached state stabilizing element in the anodic electrochromic layer is at least 0.4:1,
- (ii) the atomic ratio of the amount of the bleached state stabilizing element to the combined amount of nickel and the bleached state stabilizing elements in the anodic electrochromic layer is at least 0.025:1,
- (iii) the bleached state stabilizing element is 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, and
- (iv) the liquid mixture comprises a dispersed phase and a continuous phase, the dispersed phase comprising a dispersed species having a number average size of at least 5 nm.
A process for forming a multi-layer electrochromic structure, the process comprising:
- depositing a film of a liquid mixture onto a surface of a substrate to form a deposited film, wherein the liquid mixture comprises a continuous phase and a dispersed phase, the dispersed phase comprising metal oxide particles, metal hydroxide particles, metal alkoxide particles, metal alkoxide oligomers, gels or particles, or a combination thereof having a number average size of at least 5 nm, and;
- treating the deposited film to form an anodic electrochromic layer comprising a nickel oxide, the anodic electrochromic layer adapted to cycle between a bleached state transmissivity of at least 70% and a darkened state transmissivity of less than 30%.
