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 5 metal selected from niobium, tantalum and a combination thereof.
Claims21
A multi-layer device comprising a layer of a lithium nickel oxide composition on a first substrate, the lithium nickel oxide composition exhibiting long range ordering by X-ray diffraction analysis and comprising lithium, nickel, and at least one of niobium and tantalum, the lithium nickel oxide composition being characterized by a largest d-spacing of at least 2.5 Å.
The multi-layer device of claim 4 wherein (i) the atomic ratio of lithium to the combined amount of nickel and tantalum in the lithium nickel oxide composition is at least 0.4:1, respectively, and (ii) the atomic ratio of the amount of tantalum to the combined amount of nickel and tantalum in the lithium nickel oxide composition is about 0.025:1 to about 0.8:1, respectively.
