Single-atom Modification Strategy for Highly Stable Electrochromism

Electrochromic devices (ECDs) with reversible adjustment optical properties are gathering increasing attention in both academia and industry, exhibiting great promise in emerging energy-saving electronics, such as smart windows, and non-emissive displays. However, fabricating electrochromic devices with high cyclic stability remains challenging. In a recent work published in Cell Reports Physical Science, Zhang et al. synthesized a novel electrochromic material by modifying V2O5 using a single tungsten atom, which exhibited rich color response and excellent electrochemical redox stability, providing a new idea for practical applications of ECDs.
