Abstract:
1. A heat treated electrochromic device comprising: a) a first electrode comprising one of a cathodic electrochromic layer or an anodic counter electrode layer, b) a second electrode comprising the other of said cathodic electrochromic layer or said anodic counter electrode layer, c) an ion-conductor layer for conducting ions between said first and second electrodes, d) a first conductive layer, and e) a second conductive layer, said first and second electrodes and said ion-conductor layer being sandwiched between said first and second conductive layers, said anodic counter electrode layer comprising lithium and a mixed tungsten-nickel oxide substantially in crystalline form, and wherein the amount of nickel in said mixed tungsten-nickel oxide ranges from 15% to 90% by weight of said mixed tungsten-nickel oxide.
