1. An electrochromic element comprising:
a first electrode;
a second electrode;
an electrochromic layer disposed between the first electrode and the second electrode; and
an ion transport storage layer disposed between the second electrode and the electrochromic layer such that the ion transport storage layer is in contact with a lower surface of the electrochromic layer and an upper surface of the second electrode;
wherein when a first potential difference is formed between the first electrode and the second electrode, the electrochromic element is configured to have a first optical state in response to the electrochromic layer receiving at least one electron from the first electrode and at least one ion from the ion transport storage layer, and when a second potential difference is formed between the first electrode and the second electrode, the electrochromic element is configured to have a second optical state in response to the ion transport storage layer receiving at least one electron from the second electrode and at least one ion from the electrochromic layer,
wherein a physical structure of the ion transport storage layer is continuous, and wherein the physical structure of the ion transport storage layer and a physical structure of the electrochromic layer are discontinuous with respect to a boundary thereof.
