Abstract

Highlights

La³⁺/Na⁺ bimetallically doped vanadate, designed for the first time, is promising in many electrochemical applications (e.g., batteries, electrochromics).
This is the first report of electrochromic displays employing bimetallically doped vanadate.
It is demonstrated for the first time that zinc dendrites and vanadate dissolution are significantly inhibited by employing an aqueous hybrid Zn²⁺/Na⁺ electrolyte.

双金属掺杂钒酸盐和水性Zn2+/Na+混合电解质实现的快速稳定的锌阳极电致变色显示器。

钒酸盐是一类最有前途的显示器电致变色材料，具有多色性。然而，最近报道的钒酸盐的缓慢转换时间和钒酸盐溶解问题严重阻碍了其多样化的实际应用。在此，开发了新的策略来设计具有快速切换时间的电化学稳定的钒酸盐。我们发现，通过在V3O8中间层中引入钠和镧离子，中间层间距大大加宽，这促进了阳离子的传输并增强了电化学动力学。此外，设计了Zn2+/Na+混合电解质，以抑制钒酸盐的溶解，同时显著加速电化学动力学。因此，与任何报道的锌钒酸盐电致变色显示器相比，我们的电致变色显示产生了最快的切换时间。可以预见，具有视频速度切换的稳定的基于钒酸盐的电致变色显示器正在近距离出现。

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary and open-access journal that focus on science, experiments, engineering, technologies and applications of nano- or microscale structure and system in physics, chemistry, biology, material science, pharmacy and their expanding interfaces with at least one dimension ranging from a few sub-nanometers to a few hundreds of micrometers. Especially, emphasize the bottom-up approach in the length scale from nano to micro since the key for nanotechnology to reach industrial applications is to assemble, to modify, and to control nanostructure in micro scale. The aim is to provide a publishing platform crossing the boundaries, from nano to micro, and from science to technologies.
