“…The optical memory performance is also a crucial parameter for ECDs. 37 There was only a slight increase (1.7%) in the reflectance of the colored device after open circuit over 3.5 h, indicating an excellent optical memory effect of the device in the low-reflection state (Figure S14). Flexible electronics have attracted growing interest because their tailorable and customizable features are more versatile for different application scenarios.…”

“…The switching speed of the device in this work was faster than those of the Al-based ECDs. , In addition, the device also performed other superior metrics including larger NIR modulation (Δ R = 21.2% at 1500 nm), higher open circuit potential (∼1.36 V), and better cycling performance compared with previously reported flexible IR-ECDs based on W 18 O 49 , polypyrrole, and Prussian blue (Table S2). The optical memory performance is also a crucial parameter for ECDs . There was only a slight increase (1.7%) in the reflectance of the colored device after open circuit over 3.5 h, indicating an excellent optical memory effect of the device in the low-reflection state (Figure S14).…”

“…For example, some ECDs congurations for applications such as smart windows, goggles, e-papers and rearview mirrors, etc., have been designed to require the ability of tunable visible and near-infrared (NIR) light modulation. [72][73][74][75][76] Many requirements for EC applications in the infrared region are relatively stringent, which demands efficient manipulation of the IR light and heat through reection, transmission, and emission. Therefore, the design and preparation of IR-ECDs need to be considered for their applications in optical and thermal regulation.…”

“…Moreover, the Li 4 Ti 5 O 12 (LTO) electrode also exhibited good electrochromic performance in terms of visible and near‐infrared light modulation (54.9% at 550 nm and 71.6% at 1000 nm). [ 65 ] When assembled with a complementary NiO electrode, the rechargeable electrochromic device showed a high operating voltage of 3.0 V which could power a 1.7 V red light‐emitting diode (LED) for more than 10 min and provided an energy density of 0.2 Wh cm −3 .…”
