Prussian white (PW), due to its low cost, easy synthesis, open structure, and fast ion extraction/interaction, is introduced to the electrochromic field. The PW films were successfully grown on indium tin oxide (ITO) glass by a facial hydrothermal method. Impressively, the PW film exhibits excellent electrochemical cycling stability without obvious decay over 10 000 cycles and a high coloration efficiency of 149.3 cm2 C–1. The film also provides the large optical transmittance contrast (over 70%) in a wide wavelength range of 650–800 nm. Furthermore, the PW film shows the rapid coloration and bleaching response. These results suggest that PW is a promising practical candidate of high-performance electrochromic material.

“…According to the results presented in Figure 5 c, at the scan rate of 20 mV s −1 , the surface coverage of NW–P 2 W 17 La was determined to be 1.74 × 10 −6 mol cm −2 , which is higher than that of the tightly packed FTO–P 2 W 17 La film (3.61 × 10 −7 mol cm −2 ) [ 44 ]. Diffusion coefficients (D) of Li + ions were calculated using the Randles–Sevick equation [ 45 ]. The D value obtained for the NW–P 2 W 17 La film is 1.28 × 10 −12 cm s −1 , and that computed for the FTO–P 2 W 17 La film is 1.10 × 10 −14 cm s −1 .…”

The key challenge in the practical application of electrochromic energy storage devices (EESDs) is the fabrication of high-performance electrode materials. Herein, we deposited K7[La(H2O)x(α2-P2W17O61)] (P2W17La) onto TiO2 nanowires (NW) to construct an NW–P2W17La nanocomposite using a layer-by-layer self-assembly method. In contrast to the pure P2W17La films, the nanocomposite exhibits enhanced electrochromic and electrochemical performance owing to the 3D sea-cucumber-like microstructure. An EESD using the NW–P2W17La film as the cathode exhibited outstanding electrochromic and energy storage properties, with high optical modulation (48.6% at 605 nm), high switching speeds (tcoloring = 15 s, tbleaching = 4 s), and high area capacitance (5.72 mF cm−2 at 0.15 mA cm−2). The device can reversibly switch between transparent and dark blue during the charge/discharge process, indicating that electrochromic contrast can be used as a quantitative indicator of the energy storage status.

“…where the discharge current is represented by I, initial and final potential during galvanostatic measurements, and effective area of the electrode exposed to the electrolyte are designated by V max , V min , and A, respectively. The 2D The value of C a gradually decreased with increasing the current density, which was originated from the insufficient ion diffusion at the electrode/electrolyte interface [45].…”

Two-dimensional vanadium pentoxide inverse opal (2D V2O5 IO) architecture was fabricated by polystyrene (PS) sphere template assisted electrodeposition process. In comparison to the un-templated V2O5 film, the 2D V2O5 IO film exhibited a highly ordered hexagonal close-packed bowel-like array, as well as noticeable electrochromism, such as transmittance modulation up to 42.6% at 800 nm, high coloration efficiency (28.6 cm2 · C−1), fast ions transfer kinetic (t b = 7.2 s, t c = 2.5 s). These improvements of electrochromic performance were attributed to the ordered morphology with larger surface areas, which considerably shortened the ions diffusion paths and accelerated ions migration. An electrochromic energy storage device assembled from the 2D V2O5 IO film with simultaneous electrochromic and pseudocapacitive performance could not only show transmittance modulation accompanied by multicolor variations but also powered an LCD screen and an LED bulb, demonstrating a promising potential for practical applications.
