Process for preparing a solid, polymeric electrolyte based on polyvinyl

An electrochromic window comprises a tungsten oxide electrode on a transparent conductive glass sheet and a nickel oxide counterelectrode. The counterelectrode is activated by electrochemical intercalation of lithium on a transparent conductive glass sheet. The window also comprises a solid polymeric electrolyte interposed between the electrode and the counterelectrode. The electrolyte is formed by a solid solution of an ionic lithium compound in a solid crosslinked polyepoxide. The polyepoxide is obtained by copolymerization of a monoepoxide with a diepoxide.
