Abstract

To provide an electrochromic device, including a laminated body, which includes: at least one support; a first electrode layer on the support; an electrochromic layer on the first electrode layer; a second electrode layer disposed to face the first electrode layer; and an electrolyte layer, which fills between the first electrode layer and the second electrode layer, and is on the electrochromic layer, the at least one support including a resin substrate, and the laminated body having a desired curve formed by thermoforming.

First claim

1 . An electrochromic device, comprising:
a laminated body, which comprises: at least one support; a first electrode layer on the at least one support; an electrochromic layer on the first electrode layer; a second electrode layer disposed to face the first electrode layer; and an electrolyte layer, which fills between the first electrode layer and the second electrode layer, and is on the electrochromic layer, the at least one support comprising a resin substrate, and the laminated body having a desired curve formed by thermoforming.

2 . The electrochromic device according to claim 1 , wherein a maximum length of a major length of the at least one support on the curve of the laminated body after the thermoforming is 120% or less relative to a maximum length of a major length of the support on a flat surface of the laminated body before the thermoforming.

3 . The electrochromic device according to claim 1 , wherein a maximum length of a major length of the support on the curve of the laminated body after the thermoforming is 103% or less relative to a maximum length of a major length of the support on a flat surface of the laminated body before the thermoforming.

4 . The electrochromic device according to claim 1 , wherein at least one of the first electrode layer and the second electrode layer contains conductive metal, conductive oxide, conductive carbon, or any combination thereof.

5 . The electrochromic device according to claim 1 , wherein at least one of the first electrode layer and the second electrode layer has a laminate structure including a layer containing conductive metal or conductive carbon, and a conductive oxide layer.

6 . The electrochromic device according to claim 1 , further comprising an antideterioration layer in contact with the second electrode layer, wherein the antideterioration layer is configured to carry out a reverse electrochemical reaction to an oxidation reduction reaction of the electrochromic layer.

7 . The electrochromic device according to claim 1 , wherein the electrolyte layer is a solid electrolyte layer, and the solid electrolyte layer contains a solid solution of a matrix polymer containing an oxyalkylene chain, and an ionic liquid.

8 . A method for producing an electrochromic device, the method comprising:
thermoforming a laminated body to have a desired curve, wherein the electrochromic device comprises: a laminated body, which comprises: at least one support; a first electrode layer on the at least one support; an electrochromic layer on the first electrode layer; a second electrode layer disposed to face the first electrode layer; and an electrolyte layer, which fills between the first electrode layer and the second electrode layer, and is on the electrochromic layer, the at least one support comprising a resin substrate, and the laminated body having a desired curve formed by thermoforming.

9 . The method according to claim 8 , further comprising:
forming the first electrode layer on the at least one support; forming the electrochromic layer on the first electrode layer; forming a solid electrolyte layer on the electrochromic layer; forming the second electrode layer on the solid electrolyte layer; and forming a protective layer on the second electrode layer to form the laminated body.

forming the first electrode layer on a first support, and forming the electrochromic layer on the first electrode layer to produce a first member; forming the second electrode layer on a second support to produce a second member; and bonding the first member and the second member together with the electrolyte layer being between the first member and the second member, to form the laminated body.

11 . The method according to claim 9 , further comprising:
forming a resin layer on an outer surface of the at least one support to thicken the support, and cutting the support thickened to form a desired curve.

12 . An electrochromic dimming device, comprising:
an electrochromic device, wherein the electrochromic device comprises:
a laminated body, which comprises:
at least one support;
a first electrode layer on the at least one support;
an electrochromic layer on the first electrode layer;
a second electrode layer disposed to face the first electrode layer; and
an electrolyte layer, which fills between the first electrode layer and the second electrode layer, and is on the electrochromic layer,
the at least one support comprising a resin substrate, and the laminated body having a desired curve formed by thermoforming.
