1. A method for forming a structure having an electrochromic device therein, the method comprising:
- interposing an electrochromic device between a first adhesive interlayer and a second adhesive interlayer, wherein the first adhesive interlayer is interposed between the electrochromic device and a first substrate, and the second adhesive interlayer is interposed between the electrochromic device and a second substrate, wherein the electrochromic device comprises an electrochromic material, a solid state electrolyte, and a charge storage layer; and
bonding the electrochromic device to the first substrate via the first adhesive interlayer, and to the second substrate via the second adhesive interlayer, to form a laminated structure having the electrochromic device therein,wherein the solid state electrolyte comprises;
an electrolyte salt selected from the group of LiTFSI, LiPF6, LiBF4, LiClO4, LiCF3SO3, LiN(CF3SO2)2, LiSbFg, LiAsF6, LiN(CF3CF2SO2)2, (C2H5)4NBF4, (C2H5)3CH3NBF4, and LiI; and
a polymer matrix including one or more polar polymers crosslinked to form a network, wherein the one or more polar polymers have a semi-crystalline or crystalline microstructure.
