Electrochromic devices including a mica layer electrolyte

摘要

Electrochromic devices comprising anodic and/or cathodic electrochromic elements in combination with an ion-permeable polycrystalline mica electrolyte, the electrolyte comprising mica crystals containing exchangeable Na+, Li+ and/or H+ interlayer cations and optionally being provided as a self-supporting, flexible, transparent or opaque electrolyte sheet, are described.
