Abstract:
The present invention relates to novel transparent free-standing Al (III) incorporated Li-ion based solid-gel electrolyte for enhancement of optical contrast of  electrochromic device. More particularly, the present invention relates to Al (III) incorporated Li-ion based free-standing solid-gel electrolyte for enhancement of  optical contrast which comprises of a unique transparent, flexible, free-standing, solid-gel polymer electrolyte, its composition and process for preparation thereof. The  unique Al(iii) incorporated Li-ion based free-standing solid-gel electrolyte reveals a high optical contrast, as well as faster switching kinetics from bleached state to  colored state or vice versa on changing the external voltage. A significant increase in optical contrast from 50% to 82% is obtained with a faster switching kinetics.
