Abstract Quasi‐solid aqueous zinc ion batteries (AZIBs) based on flexible hydrogel electrolytes are promising substitutions of lithium‐ion owing to their intrinsic safety, low cost, eco‐friendliness and wearability. However, it remains a challenge lower the freezing point without sacrificing fundamental advantages such as conductivity mechanical properties. Herein, an all‐around electrolyte is constructed through convenient energy dissipation strategy via rapid reversible intramolecular/intermolecular ligand exchanges between Zn 2+ alterdentate ligands. The as‐obtained exhibits excellent properties, fatigue resistance, high Zn‐ion (38.2 mS cm −1 ), good adhesion (19.1 kPa), ultra‐low (−97 °C). Due ligands help improve solvation structure guide uniform deposition, Zn||Zn symmetric cells show stable plating/stripping behavior long‐term cycle stability. Zn||V 2 O 5 full exhibit large capacity 230.6 mAh g retention 75.2% after 1000 cycles. Furthermore, AZIBs operate stably even under extreme conditions including temperature (−40 °C) bending angle (180°). mechanically damage‐resistant can also be utilized in strain sensors. This work offers facile for developing deformation‐resistant, dendrite‐free, environmentally adaptable AZIBs.

Abstract Flexible zinc‐ion batteries have garnered significant attention in the realm of wearable technology. However, instability hydrogel electrolytes a wide‐temperature range and uncontrollable side reactions Zn electrode become main problems for practical applications. Herein, N,N‐dimethylformamide (DMF) to design binary solvent (H 2 O‐DMF) is introduced combined it with polyacrylamide (PAM) ZnSO 4 synthesize electrolyte (denoted as PZD). The synergistic effect DMF PAM not only guides 2+ deposition on Zn(002) crystal plane isolates H O from anode, but also breaks hydrogen bonding network between water improve stability electrolytes. Consequently, symmetric cell utilizing PZD can stably cycle over 5600 h at 0.5 mA cm − @0.5 mAh −2 .

Abstract The Zn//V 2 O 5 system not only faces the incontrollable growth of zinc (Zn) dendrites, but also withstands cross‐talk effect by‐products produced from cathode side to Zn anode, inducing interelectrode talk and aggravating battery failure. To tackle these issues, we construct a rapid 2+ ‐conducting hydrogel electrolyte (R‐ZSO) achieve deposition modulation reaction inhibition in full cells. polymer matrix BN exhibit robust anchoring on SO 4 2− , accelerating migration enabling dense behavior. Therefore, Zn//Zn symmetric cells based R‐ZSO can operate stably for more than 1500 h, which is six times higher that employing blank electrolyte. More importantly, effectively decouples effects, thus breaking infinite loop reactions. As result, using this modified demonstrate stable operation over 1,000 cycles, with capacity loss rate 0.028 % per cycle. Our study provides promising gel chemistry, offers valuable guide construction high‐performance multifunctional aqueous Zn‐ion batteries.

Abstract As a promising energy storage device, an aqueous zinc ion battery (AZIB) still suffers dendrite growth, hydrogen evolution, and corrosion. Hydrogel electrolyte solves the above issues to some extent. Nevertheless, mechanical properties of most hydrogel electrolytes are not competitive enough meet booming demand for flexible electronics. In this work, robust “chain‐gear” (PM‐HE) crosslinked by polymeric micelles (PMs) is constructed, in which PMs serve as “gears” form structure with polyanion chains. Specifically, support molecular chains, constructing hierarchically porous structures opening up paths Zn 2+ . Apart from crosslinkers, exist mechanism chains promote decoupling.
