Abstract The rapid development of wearable and intelligent flexible devices has posed strict requirements for power sources, including excellent mechanical strength, inherent safety, high energy density, eco‐friendliness. Zn‐ion batteries with aqueous quasi‐solid‐state electrolytes (AQSSEs) various functional groups that contain electronegative atoms (O/N/F) tunable electron accumulation states are considered as a promising candidate to the tremendous progress been achieved in this prospering area. Herein, review proposes comprehensive summary recent achievements using AQSSE by focusing on significance different groups. fundamentals challenges ZIBs introduced from chemical view first place. Then, mechanism behind stabilization functionalized is summarized explained detail. Then regarding enhanced electrochemical stability classified based polymer chain. advanced characterization methods briefly following sections. Last but not least, current future perspectives area provided authors' point view.

Abstract Harvesting the immense and renewable osmotic energy with reverse electrodialysis (RED) technology shows great promise in dealing ever-growing crisis. One key challenge is to improve output power density improved trade-off between membrane permeability selectivity. Herein, polyelectrolyte hydrogels (channel width, 2.2 nm) inherent high ion conductivity have been demonstrated enable excellent selective transfer when confined cylindrical anodized aluminum pore lateral size even up submillimeter scale (radius, 0.1 mm). The of anti-swelling hydrogel can also be further increased cellulose nanofibers. With real seawater river water, a three-chamber cell on behalf repeat unit RED system reach 8.99 W m −2 (per total area), much better than state-of-the-art membranes. This work provides new strategy for preparation hydrogel-based ion-selective membranes, owning broad application prospects fields collection, electrodialysis, flow battery so on.

The traditional liquid electrolytes pose safety hazards primarily attributed to the flammability of organic solvent, whereas solid-state can significantly enhance lithium-ion batteries. Polymer solid are being considered as an effective solution due their excellent flexibility and low cost, but they suffer ionic conductivity or high interface impedance. Here, ketone-containing allyl acetoacetate monomers were polymerized within cellulose membrane via UV photopolymerization prepare a cellulose-supported poly-allyl polymer electrolyte.
