Patent ID: 10564506

Abstract:
A method for lithiating an electrochromic device comprise forming a first transparent conductive layer on a substrate, forming an electrochromic structure on the first transparent conductive layer, forming a second transparent conductive layer on the electrochromic structure, and lithiating the electrochromic structure through the second transparent conductive layer. In one exemplary embodiment lithiating the electrochromic structure comprises lithiating the electrochromic structure at a temperature range of between about room temperature and about 500 C for the duration of the lithiation process. In another exemplary embodiment, lithiating the electrochromic structure further comprises lithiating the electrochromic structure by using at least one of sputtering, evaporation, laser ablation and exposure to a lithium salt. The electrochromic device can be configured in either a “forward” or a “reverse” stack configuration.
