Electrochromic lithium nickel group 5 mixed metal oxides

A multi-layer electrochromic device comprising:

• a first substrate comprising glass and a second substrate comprising glass;
• an anode layer comprising a liquid mixture derived layer of a lithium nickel oxide composition on the first substrate, the lithium nickel oxide composition comprising lithium, nickel, at least 0.01 wt. % carbon, and at least one of niobium and tantalum,
• a cathode layer comprising a tungsten oxide on the second substrate;
• and
• an ion conductor layer, wherein the anode layer is on one side of and in contact with a first surface of the ion conductor layer and the cathode layer is on the other side of and in contact with a second surface of the ion conductor layer.
