Embodiment 1
[0025] Such as figure 1 As shown, an electrochromic device based on a transparent metal mesh electrode consists of a four-layer structure, with a first layer 1, a second layer 2, a third layer 3 and a fourth layer 4 in sequence,
[0026] The first layer 1 is transparent conductive glass, which is FTO glass.
[0027] The third layer 3 is a zinc mesh, the inner diameter of the mesh is 1-1000 μm, the mesh is 5-300 mesh, and the transparency is 50% to 99%. In this embodiment, the inner diameter of the mesh is 50 μm and the mesh is 50. mesh, the transparency is 80% to 95%.
[0028] The fourth layer 4 is transparent and non-conductive glass for placing the third layer 3; the second layer 2 is a cavity for containing electrolyte; the first layer and the third layer are connected with wires.
[0029] Preparation steps:
[0030] (1) Electrolyte preparation: 0.1mol of ZnCl 2 Add to a small amount of deionized water and stir to mix, then add 1molKOH, stir while adding, the Zn(OH) gen...
Embodiment 2
[0039] The main difference from Example 1 lies in the preparation of the electrolyte: the ZnCl of 0.08mol 2 Add it into a small amount of deionized water and stir to mix, then add 1.6mol KOH, stir while adding, the Zn(OH) generated by the complexation reaction 4 2- , when the reaction is complete and the solution becomes clear, add deionized water to dilute to 1L to obtain 0.08M Zn(OH) 4 2- complex ionic electrolytes. The results show that it is reversible and the electrovariation effect is good.
Embodiment 3
[0041] The main difference from Example 1 lies in the preparation of the electrolyte: the ZnCl of 1mol 2 Add it into a small amount of deionized water and stir to mix, then add 4.1mol KOH, and stir while adding, the Zn(OH) generated by the complexation reaction 4 2- , when the reaction is complete and the solution becomes clear, add deionized water to dilute to 1L to obtain 1M Zn(OH) 4 2- complex ionic electrolytes. The results show that it is reversible and the electrovariation effect is good.
