Several electrochromic material systems have been described but the electrochromic phenomenon has rarely been observed in non-metallic elemental substances. Here, the authors describe iodine electrodeposition-based electrochromic windows using a water-in-salt electrolyte containing iodine ions, achieving optical contrast, near colour neutrality, and excellent cycling stability.
