Abstract Artificial interface layer engineering is an efficacious modification strategy for protecting zinc anode from dendrite growth and byproducts formation. However, the high bulk ionic conductivity of most artificial interfacial layers mainly contributed by movement anions (SO 4 2− ), which source parasitic reactions on anode. Herein, a ion donor transition (σZn 2+ = 3.89 × 10 −2 S cm −1 ) imidazole polymeric liquid (1‐carboxymethyl‐3‐vinylimidazolium bromide monomer, CVBr) Zn metal protection designed. The N + atom rings connected chains to form cavities are confined within these cavities. Thus, hindering effect surrounding units leads subdiffusive regime, inhibits diffusion SO in increases transference number. Besides, polycation‐anion coordination mechanism PolyCVBr ensures accelerated realizes rapid internal migration channel. As result, Zn@CVBr||AM symmetry cells deliver (4.42 number (tZn 0.88) simultaneously. Zn@CVBr||AM‐NaV 3 O 8 pouch display capacity retention 88.9% after 190 cycles under 90° bending, verifying their potential practical application.

Abstract The active H 2 O and slow ion kinetics behavior deteriorate the performance of aqueous zinc‐ion batteries at a wide temperature range, even in hydrogel electrolyte. Herein, component fluctuation modulated gelation effect is applied to optimize Zn 2+ solvation structure, realizing balance between activity limitation retention. as‐prepared electrolyte via situ copolymerization [2‐(methacryloyloxy)ethyl] dimethyl‐(3‐sulfopropyl) acrylamide salt matrix facilitates stable overall both normal low temperatures. Theoretical calculations experimental results attest that polymer functional groups exhibit higher efficacy substituting bound water solvated shell with content increasement, thereby alleviating water‐associated parasitic reactions. Furthermore, abundant zwitterionic not only interacts limit hydrolysis, but also constructs separated ionic migration channels promote uniform fast transport. As result, electrolytes plating/stripping behaviors over 1050 h 3000 25 −20 °C, respectively. full achieve capacity retention 98.8% 2000 cycles °C stably cycle for 600 times °C.

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.

Abstract With the wide application of portable electronic devices, zinc–ion hybrid supercapacitors (ZIHCs) have aroused great interest. However, balancing low‐temperature performance and high energy density ZIHCs remains a huge challenge.

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. Such can realize desolvation accelerate transport. Thereby, PM‐HE possesses excellent ionic conductivity (60.6 mS cm −1 ) ultrahigh transference number (0.88). Symmetrical cells stable cycling over 1500 h uniform deposition. Remarkably, has tensile (0.23 MPa) compressive (11.3 profited strengthening toughening effect PMs. The supply power stably under harsh conditions. This work proposes strategy all‐around based on reasonable design network structure, providing more possibilities practical application AZIB.
