“…Cross-linking techniques, such as chemical agents, radiationinduced cross-linking, or physical cross-linking through reversible bonds, can be employed to modify polymer-based electrolytes. Cross-linking enhances the electrolyte's resistance to mechanical deformation and improves its ability to retain ionic conductivity [39].…”

Aqueous zinc-ion batteries (ZIBs) have gained significant recognition as highly promising rechargeable batteries for the future due to their exceptional safety, low operating costs, and environmental advantages. Nevertheless, the widespread utilization of ZIBs for energy storage has been hindered by inherent challenges associated with aqueous electrolytes, including water decomposition reactions, evaporation, and liquid leakage. Fortunately, recent advances in solid-state electrolyte research have demonstrated great potential in resolving these challenges. Moreover, the flexibility and new chemistry of solid-state electrolytes offer further opportunities for their applications in wearable electronic devices and multifunctional settings. Nonetheless, despite the growing popularity of solid-state electrolyte-based-ZIBs in recent years, the development of solid-state electrolytes is still in its early stages. Bridging the substantial gap that exists is crucial before solid-state ZIBs become a practical reality. This review presents the advancements in various types of solid-state electrolytes for ZIBs, including film separators, inorganic additives, and organic polymers. Furthermore, it discusses the performance and impact of solid-state electrolytes. Finally, it outlines future directions for the development of solid-state ZIBs.

The flexible zinc–air battery has garnered ever‐growing attentions in the current decade taking advantages of the high efficiency, environmentally friendliness, and safety features. However, the sluggish ion transport and poor mechanical property hinder its realistic and mass application. To address these challenges, this study proposes a Janus strategy which combines the Grotthuss and Vehicle mechanism for OH− transport in the gel by assembling the dual network gel with LDH (layer double hydroxides) in the gel's pores. The gel can sustain 530% strain and 0.19 MPa stress without significant plastic deformation and the as‐prepared battery exhibits the high ionic conductivity as 145.93 mS cm−1 and long lifetime over 160 h. The further simulation reveals that the Grotthuss mechanism plays the determine role in the ion transport, contributing to the fast OH− transport and highly efficient flexible zinc–air battery.

Polyphenol hydrogels have found widespread application in wound healing, bone repair, drug delivery, and biosensors due to their robust wet adhesion, high ductility, and excellent self‐healing ability. However, these hydrogels often exhibit low intrinsic cohesion, which limits their overall adhesive strength. Enhancing cohesion is critical for improving both the adhesion and mechanical properties of the hydrogels, thereby expanding their utility in biomedical fields. This review begins by exploring strategies to enhance the cohesion of polyphenol hydrogel adhesives, detailing modifications that act individually or synergistically. The importance of temporally regulating cohesion is emphasized to accommodate various applications and environmental conditions. Finally, this paper discusses remaining challenges in cohesion regulation and outlines prospects for future research. It is hoped that this comprehensive review will provide new insights into the development of advanced polyphenolic hydrogel adhesives and contribute to the design of “smart adhesives” for increasingly complex needs in biomedical applications.
