“…The cycled devices remain still transparent and clear without any detectable precipitation. Although such a cycling stability is inferior to the mature five‐/seven‐layered EC windows, it still outperforms the state of the art of the bifunctional EC windows with significant energy storage ability (Table ). A further comparison of Figure S3, Supporting Information, and Figure d clearly shows the tradeoff between switching speed and cycling stability.…”

Electrochromic (EC) windows with controllable transmittances according to ambient temperature and solar irradiation strength are highly desired for energy‐efficient buildings. However, traditional EC windows operate via consuming electrical energy to trigger the chromogenic reactions, with negligible energy storage ability. Herein, a facile battery‐type Prussian blue (PB, Fe4III[FeII(CN)6]3)/Zn EC window with excellent EC properties (transmittance modulation = 84.9% at 633 nm), remarkable energy storage ability (average output voltage = 1.24 V and areal capacity = 78.9 mAh m−2), fast switching time (tbleaching = 4.1 s and tcoloring = 4.6 s), as well as an ultralong cycling lifetime (7000 cycles with 60.7% capacity retention and 92.7% transmittance modulation retention) is reported, thanks to the rational electrode and electrolyte design. As an EC window, this device can effectively promote energy efficiency and occupational comfort of buildings by regulating visible light transmittance. As a battery, this device can work as backup power or a component of smart grids, making the buildings more sustainable and functional. The design concept of this bifunctional device is helpful to further the development of next‐generation EC windows.

Reducing energy consumption is one of the major concerns in modern building design and construction because buildings account for ≈40% of the total energy consumption in modern society. Among various technologies for saving energy, electrochromic smart windows are considered as a highly promising one. Except for the application in saving energy, electrochromism has also attracted extensive attention in many other fields, such as, anti‐glare rearview mirrors, displays, military camouflage, flexible wearable fabric, etc. However, there are still many challenges needed to be solved, such as, the response rate and durability of electrochromic materials (ECMs). The transmission rate of ions in ECMs determines the response rate of the whole electrochromic device. Besides, the embedding depth and total amount of ions directly affect the contrast, durability, and coloration efficiency of ECMs. It is crucial to select suitable electrolyte ions to obtain high‐efficiency ECMs. Here, the challenges in ECMs based on ions insertion/extraction are presented, which are focused on advanced nanostructured ECMs’ design and electrochromic devices’ practical application. Recent advances in ECMs are presented to discuss the important questions, which are especially focused on the connection between suitable ions and advanced nanostructural ECMs. Finally, a perspective for next‐generation electrochromic devices is presented.

“…The assembly showed a reversible charging–discharging color contrast varying from yellow to brown and a specific capacitance of 23.34 mF/cm 2 and 92% capacitance retention after 5000 charge–discharge cycles. Lei Liu et al (2019) reported the fabrication of inorganic solid‐state layered thin film ECs obtained by magnetron sputtering of ITO/NiOx/Ta 2 O 5 /LiNbO 3 /Ta 2 O 5 /WO 3 /ITO films on glass substrate along with metallic tape as a current collector. The reported assembly showed an increased capacitance and color change with a progressive rise in temperature from 20 to 75°C.…”

Current collectors play a very crucial role in the performance of an energy storage device. Regarding supercapacitors, material design, processing, and current collectors' surface properties can result in substantial variation in energy density, power output, cyclic charge–discharge behavior, and other key performance parameters. Most of the reviews in supercapacitor materials and devices focus on the synthesis, characterization, and electrochemical properties of electrode materials. In the present report, the recent advances in supercapacitor electrodes in conjunction with current collector materials and design are summarized in light of various supercapacitor devices categorized concerning their applications and working mechanisms. It includes the literature documented on multifarious supercapacitors, that is, flow supercapacitors, alternating current line filtering supercapacitors, redox electrolyte‐enhanced supercapacitor, metal ion hybrid supercapacitors, microsupercapacitors, electrochromic supercapacitors, and self‐healing supercapacitors. To the best of authors' knowledge, this is a new and recent summarized report on the development of current collector materials based on intended applications and the working principles of supercapacitors.
