Technical Field

Background
The color-changing glass can be applied to building glass, automobile glass, aviation glass, decorative glass and the like. Currently, the most typical film layer structure of the color-changing glass is a sandwich type five-layer structure: glass/TC (transparent conductive layer)/EC (electrochromic layer)/IC (ion conductor layer)/CE (ion storage layer)/TC (transparent conductive layer)/glass. One of the most critical rings for achieving color change is IC (ion conductor layer), also known as lithium ion electrolyte layer, which must have good ionic conductivity but not electronic conductivity. Namely, the lithium ions can be repeatedly injected and extracted in the color-changing layer under the drive of voltage, and the injection and extraction are required to be performed for at least tens of thousands times according to the use characteristics of the building glass without failure. Lithium is a charge carrying tool, and a high ion migration number can make the dimming and color-changing effects of the product more excellent. It is therefore necessary to ensure high ion mobility and not to exhibit a large decay in achieving the injection and extraction of lithium ions. Side reactions are not expected to occur when the electrolyte is in direct contact with the color-changing layer or with the electrode, which requires a certain chemical stability of the electrolyte.
