Abstract
The invention pertains to an electrochromic system composed of a lithium ionic conductor electrolyte and a counter electrode symmetrical with the principal layer of electrochromic material and composed of a layer of nickel oxide, preferably deposited by reactive cathode sputtering in the presence of hydrogen-bearing plasma. The invention is used in particular for electrochromic windows, which can be used, for example, in automobile tops.
