for developing bistable displays due to their zero-energy consumption while maintaining a colored or colorless state. [3] However, operation of traditional electrochromic displays requires external voltages to trigger the coloration/bleaching processes, which makes the traditional electrochromic displays far from a netzero energy-consumption technology. The majority of the current electrochromic display research has focused on developing nanostructure electrochromic materials for fast switchings [4,5] without paying attention to how to reduce the consumed energy of the electrochromic displays.Recently, we developed a promising Zn-based electrochromic battery technology for smart windows. [6,7] The electrochromic battery exhibits self-coloration behaviors and eliminates the external voltage requirement for triggering the coloration process. The aqueous compatible Zn anode implements a much lower charged/bleached voltage for the electrochromic battery compared to the Li-and Al-based electrochromic batteries. [8][9][10] The lower charged/bleached potential indicates a lower energy consumption during the bleaching process. As such, the Zn-based aqueous electrochromic battery platform is an energy-efficient technology for reducing the energy consumption of electrochromic devices. To date, no reports exist on the utilization of electrochromic battery systems for developing energy-efficient electrochromic displays.Electrochromic materials play an important role in the development of electrochromic battery displays. Transition metal oxides (TMOs) have shown excellent electrochromic properties due to their remarkable multivalence states and the corresponding color evolutions. [11][12][13][14][15] Among the TMOs, vanadium oxide is considered the most promising material for electrochromic displays because of its multicolor behaviors. [16][17][18] However, the low electrical conductivity, significant volume expansion during cycling, and the slow reaction kinetics of bulk vanadium oxide prevent its widespread use. [19,20] In recent years, nanosized vanadium oxides have been studied to mediate these drawbacks because nanostructures provide abundant active sites on the surface and shorten the diffusion paths of ions. [20] Techniques, such as electrodeposition, [19] Electrochromic displays have attracted increased attention owing to their reversible switch of multicolors. However, the external voltage requirement for triggering the color switching makes them far from an optimum energyefficient technology. The newly developed electrochromic batteries eliminate the energy consumption for coloration while they can retrieve the consumed energy for bleaching. Such features make the electrochromic battery technology the most promising technology for energy-efficient electrochromic displays. Here, a scalable method to synthesize colloidal V 3 O 7 nanoparticles is presented, which is compatible with solution-process techniques for aqueous Zn-V 3 O 7 electrochromic battery displays. The Zn-V 3 O 7 electrochromic battery display shows an ...

“…The magnitude of the applied potential determines the level of polymer dedoped state; higher negative potentials increase the polymer film reduction and therefore magnify the intensity of the reflected light, this is true until the polymer film is being fully reduced (dedoped). In terms of the stability of the PPy film, adjusting the pH of the electrolyte solution to 7.5 did not have any negative effect on the stability of the PPy( − NaClO ) 4 compared to our previous work where the SPR transmission through the PPy-modified nanoholes array electrode was investigated. Also, the hydrogen gas bubbles potentially interrupt the optical measurements.…”

“…[1,2] The ECDs are designed to display visual information, preferably full color videos, in either reflective or transmissive mode. [1][2][3][4][5][6][7][8] Among wide range of materials which exhibit electrochromism, EC polymers have attracted remarkable interests for applications in ECDs because of their relatively high optical contrast, ease in the fabrication of large area, stability, low processing cost, low power consumption due to bistable states (doped/dedoped states), and their compatibility with flexible electronics.

Plasmonic colors are structural colors generated by the resonant interaction of light with metallic nanostructures through surface plasmons. [13] In recent years, plasmonic colors have drawn considerable attention due to their super-high printing resolution, tunable color properties, excellent chemical stability, scalable manufacturability, and environment-friendly recyclability. [13] The potentials of applying plasmonic colors in active displays have been increasingly recognized and various novel device configurations implementing plasmonic colors have been demonstrated, such as metal-nanostructures-array-based color filters for imaging devices, [14][15][16] metal-insulator-metal resonators tuned by modulating refractive index, [17,18] plasmonic color substrates controlled by liquid crystals, [19][20][21] electrochromically switchable plasmonic color devices, [22][23][24] plasmonic colors operated via reversible electrodeposition, [25,26] and aluminum nano-antenna arrays for high-chromaticity color filters in displays. [20] Recently, integrating EC polymers onto plasmonic color substrates has emerged as a very promising direction for developing ECD-based full-color flexible electronic papers. [22,24,27] From technological points of view, such device configurations offer several distinctive advantages. First, the colors are generated from the plasmonic color substrates rather than from the EC polymers, which straightforwardly breakthroughs the limited available colors of the latter. Second, through surface plasmons, plasmonic color substrates can establish strong nanoscale confinement of optical fields and thus require ultra-thin EC poly mer layer (<100 nm thick) for attaining high-contrast control of colors. The flux of material (dopant) to and from the EC polymer film during the doping/dedoping processes, upon the application of a voltage, can be significantly boosted in the ultra-thin film, which can enable unprecedented fast switching speed to display videos. [22,24] Third, plasmonic color substrates can potentially be manufactured on flexible substrates, which opens up an avenue to new applications such as next-generation wearable display devices. Promising up-scalable manufacturing techniques of plasmonic colors or structural colors include roll-to-roll (R2R) nanoimprint, [28] laser-induced photothermal reshaping, [29,30] and inkjet printing. [31,32] Out of these techniques, high-speed R2R nanoimprint has the best overall throughput and allows largearea generic plasmonic color patterns to be replicated onto flexible thin foils. [28] It is noteworthy that plasmonic color pixels manufacturable through R2R process must have surface-relief nanostructures, which are defined on a master stamp surface during its origination procedure.Combining electrochromic (EC) polymers with plasmonic colors is a very promising configuration for realizing full-color, low-power, flexible, reflective displays. From materials perspectives, the polymer material growth and its electrochemical properties, and the plasmonic color subst...

“…Electrochromic devices typically consist of a pair of complementary electrode materials on the transparent current collectors, separated by an ion-conducting electrolyte (Figure 14a), which is almost the same as the configuration of transparent supercapacitors/batteries. [202] Moreover, electrochromic materials change their color reversibly by charge insertion/extraction or chemical reduction/oxidation, which is quite similar to the reaction kinetics of electrode materials in supercapacitors or batteries. [203] For this reason, bifunctional electrochromic supercapacitors [204][205][206] and batteries [207,208] have been demonstrated as smart energy devices with the function of presenting their charging states by color change.…”
