Methods of manufacturing electrochromic devices containing a solid-state electrolyte

A method of providing an electrochromic (EC) device, the method comprising:

• providing a solid-state first electrolyte layer;
• after providing the solid-state first electrolyte layer, laminating the solid-state first electrolyte layer between a transparent first substrate and a transparent second substrate such that a transparent first electrode is disposed between the first substrate and a first side of the solid-state first electrolyte layer, and a transparent second electrode is disposed between the second substrate and a second side of the solid-state first electrolyte layer;
• and
• applying a sealant to seal the solid-state first electrolyte layer between the first and second substrates and to form the EC device;
• wherein the step of providing the solid-state first electrolyte layer comprises:
• melting a solid electrolyte material;
• extruding the melted electrolyte material;
• and
• cooling the extruded electrolyte material to form the solid-state first electrolyte layer.
