| Abstract |
.Nickel oxide (NiO), a typical electrochromic inorganic material is used in smart windows because of its advantages of good cyclic reversibility and low manufacturing cost. But it has low coloration efficiency in non-aqueous electrolyte and residue color(yellow) at bleaching state.
In this study, we synthesized cation(Co, Zr, Zn, Cu, W, Al, V) - doped NiO powders with particle sizes of 3-5 nm by simple precipitation. The electrodes with highly porous structure were prepared by wet-coating method and showed transmittance modulation at bleached state and good coloration efficiency.
Cation doped NiO and WO3 electrode were combined to fabricate a complementary electrochromic device, which shows a ΔT of 40% at 660 nm and was very stable up to 1,000 cycles in Li+ gel electrolyte. |
