Abstract

The invention belongs to the technical field of novel energy integration and discloses all solid-state electrochromic intelligent glass which has an electrochemical energy storage function and enables users to visually determine a voltage state (or an energy storage state) with naked eyes, a preparation method thereof and a self-driving energy system based on the all solid-state electrochromic intelligent glass. The all solid-state electrochromic intelligent glass structurally comprises a transparent conductive substrate, an anode material, an electrolyte, a cathode material and a transparent conductive substrate. The anode material and the cathode material are disposed on the transparent conductive substrates respectively to form an electrochromic and super-capacitor film; the electrolyte is a gel electrolyte and is filled between the anode material and the cathode material; the periphery of the gel electrolyte is packaged with epoxy resin, and finally an electrochromic device is prepared. The anode material is nickel oxide or polyaniline. The cathode material is tungsten oxide, molybdenum oxide or vanadium oxide. The self-driving energy system obtained based on the all solid-state electrochromic intelligent glass can be applied to the fields such as building curtain walls, intelligent windows for means of transport and intelligent glasses and the like.

Description

technical field [0001] The invention belongs to the technical field of new energy integration, and in particular relates to an all-solid-state electrochromic smart glass with electrochemical energy storage and a voltage state (or energy storage state) that can be visually judged by the naked eye and a preparation method thereof; Self-powered energy system for color-changing smart glass. Background technique [0002] Supercapacitor, also known as electrochemical capacitor, is a new, efficient and practical energy storage device with performance between batteries and traditional capacitors. It has the advantages of high power density, long service life, and environmental friendliness. According to different energy storage mechanisms, supercapacitors are generally divided into electric double layer capacitors and pseudocapacitors. The electrode materials of the former are generally porous carbon materials, and the electrode materials of the latter are generally transition metal...
