Fast and Stable Zinc Anode-Based Electrochromic Displays Enabled by Bimetallically Doped Vanadate and Aqueous Zn²⁺/Na⁺ Hybrid Electrolytes.

ABSTRACT: Vanadates are a class of the most promising electrochromic materials for displays as their multicolor characteristics. However, the slow switching times and vanadate dissolution issues of recently reported vanadates significantly hinder their diverse practical applications. Herein, novel strategies are developed to design electrochemically stable vanadates having rapid switching times. We show that the interlayer spacing is greatly broadened by introducing sodium and lanthanum ions into V₃O₈ interlayers, which facilitates the transportation of cations and enhances the electrochemical kinetics. In addition, a hybrid Zn²⁺/Na⁺ electrolyte is designed to inhibit vanadate dissolution while significantly accelerating electrochemical kinetics. As a resu
