Abstract

The invention relates to a solid electrolyte material. The chemical composition of the solid electrolyte material is LixSiyRezSmOn, wherein x is larger than or equal to 2 and smaller than or equal to3, y is larger than or equal to 0.5 and smaller than or equal to 2, z is larger than or equal to 0.3 and smaller than or equal to 0.6, (m+n) is larger than (x+4y+3z)/2.1 and smaller than or equal to (x+4y+3Z)/1.8, and Re is selected from rare earth elements Y, Gd, Gy or Sm. The solid electrolyte material is high in lithium ion conductivity, high in electron conductivity, wide in electrochemical window and high in temperature resistance. The invention further relates to a solid electrochromic device. An electrolyte is selected from the solid electrolyte material, an electrochromic layer is selected from at least one of tungsten oxide, bismuth trioxide, molybdenum trioxide or nickel oxide, and an ion storage layer is selected from at least one of lithium-embedded vanadium pentoxide, lithium-embedded titanium dioxide, lithium-embedded tungsten trioxide or lithium-embedded nickel oxide. The solid electrochromic device has the advantages of being short in color change response time and stable in performance.

Description

technical field [0001] The present invention relates to the field of electrochromism, more particularly to solid electrolyte materials of all-solid electrochromic devices, solid electrochromic windows, solid electrochromic mirrors and preparation methods thereof. Background technique [0002] Electrochromism means that under the action of an external electric field, a material undergoes a redox reaction or changes in the injection or extraction of charges (electrons or ions) within the molecular structure, resulting in the optical properties of the material such as transmittance, absorptivity and reflectivity. Reversible changes occur in the visible, infrared or ultraviolet regions. The technology has very important application value in the fields of architectural glass, intelligent color-changing windows for vehicles, aircraft portholes, color-changing sunglasses, automotive rear-view mirrors, information display and military technology. [0003] A typical all-solid-state ...
