Inhibiting Vanadium Dissolution of Potassium Vanadate for Stable Transparent Electrochromic Displays.

ABSTRACT: Vanadium oxides are highly valued as electrochromic materials because of their multicolor capabilities. However, their practical applications have been limited due to challenges such as the dissolution of vanadate into aqueous electrolytes, leading to poor long-term stability. Herein, a solution is proposed to the vanadate dissolution issue by utilizing a hybrid electrolyte consisting of tetraethylene glycol dimethyl ether (TEGDME) and water. This electrolyte has the unique ability to form a robust cathode electrolyte interface layer on vanadium oxide electrodes. As a proof of concept, zinc-anode-based multicolor transparent electrochromic displays are prepared using layered potassium vanadate (K₂V₆O₁₆·1.5H₂O, KVO) with a TEGDME-water hybrid elec
