Present challenges in electrochromic devices include the limited transmissive and reflective inter‐switchability, while achieving high optical contrast, fast switching speed, and cycling stability, simultaneously. In article number 1903198, Pooi See Lee and co‐workers develop a quasi‐solid‐state tristate reversible electrochemical mirror device, which offers highly reversible switching between transparent, greyish‐blue, and mirror (reflective) optical states. The alloying approach facilitates the electrodeposition and dissolution of Cu mirror film, allowing enhanced device stability.

可逆电化学镜设备：具有增强稳定性的准固态三态可逆电化学镜设备（Adv。Sci。13/2020）

电致变色设备当前面临的挑战包括有限的透射和反射互换性，同时要实现高光学对比度，快速切换速度和循环稳定性。Pooi See Lee及其同事在编号1903198中开发了一种准固态三态可逆电化学镜装置，该装置可在透明，灰蓝色和镜（反射）光学状态之间提供高度可逆的切换。合金化方法有助于电沉积和溶解铜镜面膜，从而增强了器件的稳定性。
