“…Response time (t), defined as the time needed for transmittance to change by 90%, is an essential factor in evaluating electrochromic performance. [48][49][50] We therefore measured the speed of electrochromic response between different operating modes from the transmittance spectra in real-time. The switching speed from the ''bright'' to the ''cool'' mode as measured at 1600 nm (Fig.…”

“…Very recently, Lee and co‐workers reported an ultrathin ZIB by assembling the electrochromic cathode (Fe‐HCF), gel electrolyte, and Zn anode (Figure 7j). [ 117 ] Figure 7k shows the transmittance spectrum of the FQAZIB implying the oxidation of Fe‐HCF is the coloration process and the reduction of Fe‐HCF is the discoloration process. Besides, two FQAZIBs connected in series can power a yellow light‐emitting diode (LED, forward voltage of 2.0 V) (Figure 7l).…”

The commercial traditional energy storage devices such as lithium-ion batteries and sodium-ion batteries are bulk and stiff, which hardly meet the requirements of flexible and wearable electronics. [2] Thus, seeking the power sources with high safety, reliability, and flexibility is highly urgent. [3] Aqueous zinc-ion batteries (AZIBs) have attracted a lot of interests with the features of inherent safety, plentiful reserves, low standard redox potential of Zn/Zn 2+ of −0.76 V versus the standard hydrogen electrode (SHE), and facile fabrication process. [4] Besides, the mild or weak acid aqueous electrolytes deliver higher conductivity and safety than organic electrolytes, implying the favorable power density of AZIBs. [5] These virtues endow the AZIBs present marvelous potential application in flexible electronic devices, under a condition that the AZIBs possess excellent flexibility via adopting flexible current collector and flexible packaging materials. [6] However, when the flexible AZIBs based on liquid electrolyte undergo various mechanical deformations, the occurrence of electrolyte leakage may jeopardize the cyclic performance of the batteries. [7] Moreover, the aqueous liquid Aqueous zinc-ion batteries (AZIBs) may have applications in macroscale energy storage on account of their advantages of high-safety, cost-effectiveness, and ecofriendliness. As a promising application, flexible quasi-solidstate AZIBs (FQAZIBs) can withstand mechanical deformation, and can act as favorable power supply devices for wearable electronics. As FQAZIBs are one of the most exciting and rapidly ongoing topics among aqueous batteries, it is critical yet timely to summarize the latest development in this field, providing the much-needed guidance for the fabrication of FQAZIBs. In this review, the recent progress and rational design strategies for FQAZIBs from mechanisms, design principles, and applications are systematically presented. First, the energy storage and flexible mechanisms of FQAZIBs are illuminated in detail. Subsequently, the design philosophies of FQAZIBs are also systematically elucidated. Moreover, the latest progress and practical applications of FQAZIBs in wearable electronics are reviewed in detail according to various functions such as compressibility, stretchability, electrochromic ability, anti-freezing ability, self-healing ability, self-charging properties, photodetecting function, shape memory, biodegradability, and actuated function. Finally, some applications and promising prospects in the research area of FQAZIBs are demonstrated to supply guidelines on the exploitation of their practical applications.

“…Emerging multivalent ions, such as Zn 2+ , Ca 2+ , and Al 3+ , have also been studied for MERABs because of the rich electron transfer which can offer a high volumetric energy density together with excellent optical modulation [ 18 , 99 , 100 ]. Given the low redox potential (− 0.76 V vs. SHE) and high gravimetric capacity (820 mAh g −1 ) of Zn 2+ , Elezzabi et al [ 35 , 101 ] successfully carried out a series of studies for zinc-based MERABs, including self-recharged MERABs and solar-charging MERABs, which show great potential to reduce energy consumption in low-carbon society.…”

Multifunctional electrochromic-induced rechargeable aqueous batteries (MERABs) integrate electrochromism and aqueous ion batteries into one platform, which is able to deliver the conversion and storage of photo-thermal-electrochemical sources. Aqueous ion batteries compensate for the drawbacks of slow kinetic reactions and unsatisfied storage capacities of electrochromic devices. On the other hand, electrochromic technology can enable dynamically regulation of solar light and heat radiation. However, MERABs still face several technical issues, including a trade-off between electrochromic and electrochemical performance, low conversion efficiency and poor service life. In this connection, novel device configuration and electrode materials, and an optimized compatibility need to be considered for multidisciplinary applications. In this review, the unique advantages, key challenges and advanced applications are elucidated in a timely and comprehensive manner. Firstly, the prerequisites for effective integration of the working mechanism and device configuration, as well as the choice of electrode materials are examined. Secondly, the latest advances in the applications of MERABs are discussed, including wearable, self-powered, integrated systems and multisystem conversion. Finally, perspectives on the current challenges and future development are outlined, highlighting the giant leap required from laboratory prototypes to large-scale production and eventual commercialization.
