Abstract
The present application discloses a method for preparing an electrochromic device. The method includes placing an edge protection material on a first and second substrates, placing a first and second interlayers respectively within the edge protection material on the first and second substrates, wherein the edge protection material surrounds edges of the first and second interlayers, and interposing an electrochromic film between the first and second interlayers. The edge protection material prevents chemicals in the first and second interlayers from entering into the electrochromic film.

An electrochromic device comprising:
- an electrochromic film comprising a first electrode layer and a second electrode layer facing the first electrode layer of the electrochromic film, wherein:
- an edge of the first electrode layer is cut such that a portion of an inner surface of the second electrode layer is exposed, and
- an edge of the second electrode layer is cut such that a portion of an inner surface of the first electrode layer is exposed, the edge of the first electrode layer and the edge of the second electrode layer are opposing edges;
- a first edge protection material sealing the exposed portion of the inner surface of the second electrode layer;
- and
- a second edge protection material sealing the exposed portion of the inner surface of the first electrode layer.
