“…PAM is a typical water-soluble polymer with good transparency, biocompatibility, excellent mechanical strength, plasticity and high ionic conductivity. [52,53] The use of PAM in electrochemical systems is attractive because it eliminates the use of organic solvents (such as PC) for dissolution since it is highly hydrophilic. Additionally, it can easily form hydrogen bonds with other compatible molecules due to the presence of amide group and this often results in higher conductivity.…”

The interest in all solid organic based electrochromic devices (ECDs) is on the increase. This is because these devices offer the applicability of electrochromic materials in products such as smart sensors, smart windows, flexible wearables and energy storage devices. The use of quasi‐solid electrolytes for the construction of these ECDs is attractive because of their ease of preparation, availability, low cost, improve electrochromic performance, good ionic conductivity and prevention of leakages in ECDs. Hence, in this review, a detailed discussion is presented on the progress in the development of semi‐solid electrolytes for ECDs fabrication. The preparation of the most common electrolytes that have been applied for organic based ECDs are summarized. Particular attention is given to efforts and strategies that have been adopted to improve the efficiency of quasi‐solid electrolytes. Importantly, knowledge gaps that warrant further research are clearly identified and recommendations for future works are suggested. This review will be very beneficial for both established and new researchers in the field of electrochromic devices and material science.

“…12–15 Compared with traditional LIBs and supercapacitors, lithium rechargeable batteries with hydrogel electrolytes are an excellent energy storage candidate due to their superior characteristics, such as safety, nontoxicity, decent energy/power density, appropriate operating voltage, and ability to withstand various deformation levels. 16–19 These advantages make hydrogel electrolyte-based LIBs ideal flexible energy-storage units for photo-rechargeable devices. However, shortcomings still exist, such as most hydrogels tend to freeze at low temperatures (below 0 °C), causing them to become rigid and fragile, which results in the loss of their desirable properties.…”

Aqueous iodine batteries (AIBs) with reversible iodine redox activity are considered a viable candidate for stationary energy storage units and thus have recently drawn extensive research interest. Herein, we introduce an aqueous manganese iodine battery (AMIB), utilizing sodium iodide (NaI) as a redox‐active in the Mn(ClO4)2 (NMC) electrolyte, activated carbon (AC) as a redox host and Mn ions as the charge carrier. Taking advantage of enhanced kinetics facilitated by I2/2I‐ redox activity, our suggested AMIBs can be electrochemically charged/discharged with only a 5% loss in capacity after 2,000 cycles at a low current density of 0.3 A g‐1 in an AC||AC coin cell configuration. Moreover, the AC||Zn‐Mn hybrid full‐cell configuration is also established with AC and a Zn‐Mn anode involving the NMC electrolyte, which retains a high energy of 185 Wh kg‐1 at a specific power of 2,600 W kg‐1.
