Title: Electrochromic devices and related products and methods

Abstract

An electrochromic device may be switchable between a transparent state and at least one reflective state. A lithium-containing reflective feature may form when the electrochromic device is switched from the transparent state to the reflective state. Various products and methods may involve the electrochromic device.
