1. An electrochromic device formed by a process comprising:

  • providing a plurality of layers including;

    a first electrode comprising one of a cathodic electrochromic layer or an anodic counter electrode layer,a second electrode comprising the other of the electrochromic layer or the anodic counter electrode layer,an ion-conductor layer between the first and second electrodes,a first conductive layer, anda second conductive layer, the first and second electrodes and the ion-conductor layer being sandwiched between the first and second conductive layers, and the anodic counter electrode layer comprises a mixed tungsten-nickel oxide and lithium; and

    heating the plurality of layers at a temperature ranging from 355°

    C. to about 500°

    C. to react the mixed tungsten-nickel oxide and lithium.
