New topic: Electrochromic windows/smart glass and their reaction

I saw in the internet that the reaction of smart glassed that turn blue due to electrical stimulus was:
LiWO₃= Li+ + WO₃
(Its a redoxreaction)
But im not sure how the individual reduction and oxidation of the reaction is supposed to go, could someone explain?

Thank you!

Thank you!
I had read that article already and I still don't understand all of it. For example, in the article they mention that the electrical stimulus is only needed to change the windows and not to mantain the dark or light state. I dont understand how that can be posible. Do you have any insights on that?

Absolutely! The concept you're referring to is known as "bistable" electrochromic windows. Essentially, these windows need an electrical stimulus only to change their state from dark to light or vice versa, but once they've changed, they remain in that state without any additional power. This is possible because the materials used in these windows have stable states that do not require continuous power to maintain. It's like flipping a switch that stays in position until you actively change it again. This helps in reducing the overall energy consumption.
