The multisensory responsiveness of hydrogels positions them as promising candidates for artificial skin, whereas the mismatch modulus between soft and hard electrodes well poor adhesion conductance at interface greatly impairs stability electronics devices. Herein, we propose an in situ postprocessing approach utilizing electrochemical reactions metals (Zn, etc.) to synergistically achieve strong hydrogel-electrode interface, low interfacial impedance, local strain isolation due structural densification hydrogel network. mechanism is that Zn electrochemically oxidizes

Abstract The practical applications of aqueous Zn/I 2 batteries (AZIBs) operating within a wide temperature range are severely hindered by the uncontrolled shutting polyiodide ions (I 3 − / I 5 ) and rampant side reactions. In this study, tolerant polyanionic hydrogel (borax‐bacteria cellulose p (AMPS‐AM)) with ion selective permeability is designed for inhibiting effect reactions under extreme temperatures from −50 to 50 °C. zincophilic R−SO significantly enhances transport Zn 2+ cations promotes uniform growth metal along (002) plane. Moreover, abundant hydrophilic groups in hydrogels effectively suppress both hydrogen evolution reaction formation by‐products reducing water reactivity. Furthermore, theoretical calculations, visualization experiment situ Raman spectroscopy confirm that group hinders shuttle process /I anions through electrostatic repulsion. Consequently, gel electrolyte facilitates ultra‐stable full cell at low current density C over 100 A pouch negative/positive capacity ratio 3.3 exhibits stable performance 350 cycles an impressive high‐areal 2.03 mA h cm −2 , thereby establishing solid foundation its applications.

The practical applications for aqueous Zn ion batteries (ZIBs) are promising yet still impeded by the severe side reactions on metal. Here, a lysozyme protective layer (LPL) is prepared metal surface simple and facile self-adsorption strategy. LPL exhibits extremely strong adhesion to provide stable interface during long-term cycling. In addition, strategy triggered hydrophobicity-induced aggregation effect endows with gap-free compacted morphology which can reject free water effective reaction inhibition performance. More importantly, conformation transformed from α-helix β-sheet structure before formation, thus abundant functional groups exposed interact

Abstract Fiber‐shaped aqueous zinc‐ion batteries (FAZIBs) with intrinsic safety, highcapacity, and superb omnidirectional flexibility hold promise for wearable energy‐supply devices. However, the interfacial separation of fiber‐shaped electrodes electrolytes caused by Zinc (Zn) stripping process severe Zn dendrites occurring at folded area under bending condition seriously restricts FAZIBs' practical application. Here, an advanced confinement encapsulation strategy is originally reported to construct dual‐layer gel electrolyte consisting high‐fluidity polyvinyl alcohol‐Zn acetate inner layer high‐strength alginate outer anode. Benefiting from synergistic effect inner‐outer formation solid interphase on anode surface lysine additive, resulting Zn‐Zn symmetric cell delivers long cycling life over 800 h 1 mA cm −2 dynamic frequency 0.1 Hz. The finite element simulation further confirms that can effectively suppress arising process. More importantly, a robust twisted Zn/zinc hexacyanoferrate battery based successfully assembled, achieving remarkable capacity retention 97.7% after 500 cycles. Therefore, such novel design paves way development long‐life metal batteries.

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 . Furthermore, Zn//PZD//MnO full exhibits favorable adaptability (for 16000 cycles 3 A g −1 under 25 °C, 750 98 0.1 ‐20 °C) outstanding mechanical properties lighting up LEDs conditions pressure, bending, cutting, puncture). This work proposes useful modification designing high‐performance electrolyte, which provides reference investigating flexible aqueous batteries.
