Abstract

The invention relates to an aluminum-lithium alloy solid-state ion conduction layer and a preparation method thereof and a full-solid-state electrochromic device containing the solid-state ion conduction layer. The chemical constitution of the solid-state ion conduction layer is aluminum-lithium alloy AlxLi, wherein x is more than 0 and less than 1; the solid-state ion conduction layer is cheap and easy to obtain and can be used for conducting lithium ion between a first electrochromic layer and a second electrochromic layer of the electrochromic device so as to realize the electrochromism, thereby improving the conductivity and conduction speed of the ion between two electrochromism layers.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a solid-state ion-conducting layer material and its corresponding all-solid-state electrochromic device and a preparation method, which are mainly used in application fields such as electrochromic glass, moving windows and devices. Background technique [0002] The ion conducting layer can be classified into a solution type, a gel type, a solid type, and the like according to the form of the film material. Compared with solution-type and gel-type electrochromic devices due to poor adhesion and easy leakage, the solid-state ion-conducting layer has more research value. An electrochromic device containing a solid-state ion-conducting layer and a thin-film structure that is all solid is called an all-solid electrochromic device, and generally includes a cathode, a first color-changing layer, an ion-conducting layer, a second color-changing layer, a dielectric layer, and an anode. ...
