Abstract:
A method for producing an electrochromic device which comprises the steps of (a) assembling a hollow cell constituting an electrochromic device by sealing together the entire peripheral edges of two electrically conductive substrates, at least one of which is transparent, disposed in a spaced-apart opposing relationship with each other and providing at least a portion of the sealed edges with an opening, whose surroundings are formed by a member of a material which is deformable by press, having a passage extending not perpendicular to the end surface of the opposed substrates; (b) vacuum-injecting an electrolyte or the precursor thereof through the opening into the cell; (c) closing the opening and passage by press deforming the surroundings after completing of the injection; (d) sealing the closed opening with an adhesive.
