| 英文摘要 | V2O5, which has multicolor and energy storage properties, is a promising electrochromic material for multifunctional electrochromic devices, but its practical application is limited by its poor lifespan and long switching time. In this work, high-performance V2O5/TiO2 films were fabricated by spraying a V2O5 solution on in situ-grown TiO2 nanorods. Due to the porous structure formed between the TiO2 nanorods and the remarkable electron transfer performance of TiO2, the switching time of the V2O5/TiO2 films decreased. Moreover, the strong adhesion between the TiO2 nanorods and F-doped tin oxide (FTO) glass and the increased surface roughness of the substrates significantly improved the cycling stability of the V2O5/TiO2 films. With a large transmittance modulation (47.8% at 668 nm), fast response speed (tau(c) = 5.1 s, tau(b) = 4.2 s), and long lifespan, V2O5/TiO2 films were used as electrodes for the electrochromic energy storage device (EESD), which switched in six colors through color overlay: dark orange, sandy yellow, green-yellow, yellow-green, dark green, and dark brown. Inspired by pixel displays, EESDs were designed by segmenting V2O5 films to stagger the display of the electrochromic and ion storage layers, which presented 11 types of information based on different combinations of colors. This work provides inspiration for developing multifunctional electrochromic devices, especially for camouflage and information displays. |
