Abstract Quasi‐solid‐state aqueous zinc ion batteries suffer from anodic dendrite growth during plating/stripping processes, impeding their commercial application. The inhibition of dendrites by high‐modulus electrolytes has been proven to be effective. However, hydrogel are difficult achieve high modulus owing inherent water contents. This work reports a electrolyte with ultrahigh that can overcome the stress through mechanical suppression effect. By combining wet‐annealing, solvent‐exchange, and salting‐out processes tuning hydrophobic crystalline domains, is obtained substantial content (≈70%), (198.5 MPa), toughness (274.3 MJ m −3 ), zinc‐ion conductivity (28.9 mS cm −1 which significantly outperforms previously reported poly(vinyl alcohol)‐based hydrogels. As result, exhibits excellent dendrite‐suppression effect achieves stable performance in Zn||Zn symmetric (1800 h cycle life at 1 mA −2 ). Moreover, Zn||V 2 O 5 pouch display cycling operate stably even under extreme conditions, such as large bending angle (180°) automotive crushing. provides promising approach for designing mechanically reliable advanced batteries.

The uncontrolled dendrite growth and detrimental parasitic reactions of Zn anodes currently impede the large-scale implementation aqueous zinc ion batteries. Here, we design a versatile quasi-solid-state polymer electrolyte with highly selective transport channels via molecular crosslinking sodium polyacrylate, lithium magnesium silicate cellulose nanofiber. abundant negatively charged ionic modulate Zn2+ desolvation process facilitate transport. Moreover, an in-situ formed Zn-Mg-Si medium-entropy alloy on anode allows for improved nucleation kinetics homogeneous deposition. These combined advantages enable to achieve average Coulombic efficiency 99.7 % over 2400 cycles reversible cycling up 600 h large depth discharge 85.6%. resultant | |V2O5 offers stable long-term performance its pouch cell achieves capacity 1.13 Ah at industrial-level loading mass 31.3 mg. pose significant challenges application zinc-ion authors report quasi solid-state engineered enhanced battery performance.

Abstract Aqueous zinc‐metal batteries are prospective energy storge devices due to their intrinsically high safety and cost effectiveness. Yet, uneven deposition of zinc ions in electrochemical reduction side reactions at the anode interface significantly hinder development application. Here, we propose a solvation‐interface attenuation strategy enabled by frustrated tertiary amine amphiphilic dipolymer electrolyte additive. The configuration superhydrophilic segments with covalently bonded lipophilic spacers enables coupled steric hindrance/coordination, which establishes balanced push‐pull dynamic dipolymer‐H 2 O‐Zn 2+ . Such interplay reconstructs solvation structure Zn allows formation stable dipolymer‐inorganic hybrid solid (SEI) layer. This SEI layer effectively shields from water anions, reducing reactions. In addition, adsorbed regulates interfacial kinetics ensures uniform deposition. As result, Zn−Zn symmetric cells dipolymer‐containing exhibit remarkable cycling stability exceeding 5800 h (242 days). Zn‐NVO Zn‐AC ion supercapacitors also deliver for up 1440 (60 days) high‐capacity retention over 80 %. research demonstrates potential facilitate commercialization zinc‐based storage devices.

The solar-driven photorechargeable zinc-ion batteries have emerged as a promising power solution for smart electronic devices and equipment. However, the subpar cyclic stability of Zn anode remains significant impediment to their practical application. Herein, poly(diethynylbenzene-1,3,5-triimine-2,4,6-trione) (PDPTT) was designed functional polymer coating Zn. Theoretical calculations demonstrate that PDPTT not only significantly homogenizes electric field distribution on surface, but also promotes ion-accessible surface With multiple N C=O groups exhibiting strong adsorption energies, this reduces nucleation overpotential Zn, alters diffusion pathway

Non-uniform zinc plating/stripping in aqueous zinc-ion batteries (ZIBs) often leads to dendrites formation and low Coulombic efficiency (CE), limiting their large-scale application. In this study, a pre-corroded Zn (PC-Zn) anode with 3D ridge-like structure is constructed by facile solution etching sodium hypophosphite (NaH
