Rapid response and wide-band regulation of an electrochromic device achieved by ultra-small V2O5 nanodots and a Zn2+/Li+ electrolyte

A multi-color transparent electrochromic display with a zinc anode was developed using V 2 O 5 nanodots and a Zn 2+ /Li + electrolyte, achieving wide-band adjustments of vanadate devices and exhibiting excellent electrochromic performance.
