Inorganic materials have been extensively studied for visible electrochromism in the past few decades. However, the single inorganic electrochromic (EC) material commonly exhibits a single color change, leading to a narrow spectrum of modulation, which offsets or limits the maximally energy-saving ability. Here, we present a wide-spectrum modulated EC device designed by combining the complementary EC nanocomposite of manganese dioxide (MnO 2 ) and Prussian blue (PB) for enhanced energy savings. Porous MnO 2 nanostructures serve as host frameworks for the templated growth of PB, resulting in MnO 2 /PB nanocomposites. The complementary optical modulation ranges of MnO 2 and PB enable a widen-spectrum modulation across the solar region with the development of the MnO 2 /PB nanocomposite. The colored MnO 2 /PB device exhibited an optical modulation of 32.1% in the wide solar spectrum range of 320−1100 nm and blocked 72.0% of the solar irradiance. Furthermore, fast switching responses (2.7 s for coloration and 2.1 s for bleaching) and a high coloration efficiency (83.1 cm 2 •C −1 ) of the MnO 2 /PB EC device are also achieved. The high EC performance of the MnO 2 /PB nanocomposite device provides a new strategy for the design of highperformance energy-saving EC smart windows.

“…Electrochromic devices are synonymously associated with dynamic windows, nonemissive dynamic displays, and optically tunable materials. This aesthetic technology has great potential in energy-saving architectural buildings and automotive, augmented visual reality, and wearable displays. − Nevertheless, electrochromic technology has yet to realize widespread adoption due to its limited optical states, slow response, and poor durability. Conventional electrochromic technology has mainly focused on developing nanostructured inorganic materials, organic polymers, inorganic–organic blends, and viologens. − Electrochromic devices based on reversible metal electrodeposition/dissolution − that switch between clear and colored states are viewed as exciting alternatives to traditional smart glass, − offering high contrast and durability.…”

Reversible electrochemical mirror (REM) electrochromic devices based on reversible metal electrodeposition are exciting alternatives compared with conventional electrochromic because they offer electrochemical tunability in multiple optical states, long durability, and high contrast. Different from conventional electrochromic materials, of which the color change depends on the intercalation/deintercalation of ions into electrochromic films, the change in the optical states of REMs is based on the reversible electrodeposition and dissolution of metal. In this study, a REM electrochromic device with a Cu hybrid electrolyte composed of aqueous and nonaqueous components is proposed, which serves as an electrolyte reservoir that hosts Cu ions for reversible electrodeposition/dissolution. The hybrid electrolyte promotes the electrochemical reversibility of the Cu redox, an enhanced electrochromic performance, and a robust cycling stability of 5000 cycles (minor degradation of 4.71%). The investigation of the discharging/charging of the Cu hybrid REM device reveals that the Cl–/ClO– redox mechanism occurs at the cathode. Finally, an unprecedented dual-functional Cu hybrid REM energy storage device has been realized.

Organic materials are always viewed as promising electrochromic (EC) materials due to their synthetic versatility, color tunability, ready processability, and derivability from sustainable feedstocks. Most organic materials, however, are prone to undesirable redox side reactions in the presence of oxygen and water. As such, redox–active organic layers are often used in tandem with organic electrolytes to preserve their electrochemical stability. With the growing interest in electronics that are environmentally sustainable and biologically safe, developing aqueous‐compatible organic materials is gaining growing interest. Herein, a rationally designed iron terpyridyl coordination polymer (CP) is prepared by controlled electropolymerization for realization of aqueous compatible EC and energy storage applications. Detailed analysis is established, showing that the CP grows in a 1D fashion and exhibits a predominant capacitive behavior which is reflected from its rapid charge–transfer kinetics. Taking this as an advantage, an integrated hybrid electrochromic zinc battery device is demonstrated with high color contrast, fast response time, and good endurance.
