WO3 film is as one of the most commonly used inorganic electrochromic materials and the most popular smart insulating material, so it is often used to obtain a smart sun room, to play the role of heat insulation, heat preservation and UV-shielding.

Therefore, in order to obtain a sun room with high heat insulation and high heat preservation, it is necessary to do the performance test on the WO3 film electrochromic material such as cyclic voltammetry. The injection/extraction of Li+ ions is an important characteristic of electrochromic materials, and it is a key performance indicator for judging the performance of electrochromic materials. For the ability to exchange charge and other electrochromic properties of electrochromic materials, we generally use the basic measurement method in electrochemistry, namely cyclic voltammetry. Cyclic voltammetry is to add a symmetrical triangular wave sweep voltage to a constant-area working electrode and record the current-to-voltage response curve, that is, the I-U curve.
