Published: April 1, 2025

The cathode materials set the limitation of aqueous zinc ion batteries (AZIBs) in capacity and restrict their development. Vanadium-based show unsatisfactory conductivity strong interactions with Zn2+ as well a narrow voltage window. Herein, an integrated network structure is obtained by modulating window to phase transition from VO2 HXV2O5. This has multiple advantages: low crystallinity abundant active sites; good electrolyte wetting; two-electron transfer for high specific capacity. AZIBs exhibit impressive rate performance (545 mAh g-1 at 0.1 A 185 20 g-1) cycling (179 after 15 000 cycles g-1), stable operation even -20 °C (391 1 g-1, 97 10 g-1). have power density energy based on mass material (405 Wh kg-1 74 W 102 11 127 kg-1). pouch-type cell can run over 500 h, maximum 45.5 kg-1. mechanism storage are identified, which conducive promoting development cathodes AZIBs.

Quaternary Alloy Interfaces for Stable Zinc Anodes for High‐Performance Aqueous Zinc‐Ion Batteries With Long‐Term Cycling Stability

Small, Journal Year: 2025, Volume and Issue: unknown

Published: May 2, 2025

Abstract Aqueous zinc‐ion batteries (AZIBs) have emerged as a promising energy storage solution owing to their intrinsic safety, low cost, environmental friendliness, and high theoretical specific capacity. However, practical application is hindered by uncontrollable dendrite growth side reactions at the zinc metal anode. To address these challenges, simple cost‐effective electrodeposition strategy proposed construct quaternary Zn‐Cu‐Sn‐Bi alloy artificial interface layer on foil (ZCSB@Zn) anode of AZIBs. Density functional theory (DFT) calculations in situ optical observation confirm that this dense reduces migration barrier weakens hydrogen adsorption, facilitating uniform deposition while effectively suppressing formation. The symmetric ZCSB@Zn cell exhibits extraordinary cycle stability exceeding 8000 h. Furthermore, assembled ZCSB@Zn//CSB‐MnO 2 full demonstrates capacity 199 mAh g −1 1 A , maintaining even under loading 10 mg cm −2 temperature conditions (50 °C). This study presents scalable for constructing layers anodes, highlighting potential AZIB applications.

Ternary Gel Electrolyte Enabling Wide‐Temperature and High‐Rate Performance in Aqueous Zinc‐Ion Batteries

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: May 7, 2025

Abstract Aqueous zinc‐ion batteries (AZIBs) offer significant potential for grid‐scale energy storage due to their cost‐effectiveness, safety, and eco‐friendliness. However, interfacial instability parasitic reactions under extreme temperatures (−20 60 °C) severely degrade cyclability. To address these limitations, a ternary copolymer gel electrolyte (PAM‐T‐S) is developed through copolymerization of acrylamide (AM) with [2‐(methacryloyloxy)ethyl]dimethyl(3‐sulfopropyl)ammonium betaine (SPE) thymine (Thy), forming multidimensional crosslinked network. Thy immobilizes free water molecules suppress activity, while SPE establishes rapid Zn 2+ transport pathways, boosting ionic conductivity. Synergistically, reconstruct the solvation sheath induce hybrid organic–inorganic solid interphase (SEI) via preferential adsorption decomposition, effectively inhibiting dendrite growth side reactions. Consequently, Zn||Zn symmetric cells PAM‐T‐S achieve long lifespans 3200 h at 1 mA cm −2 /1 mAh 1000 20 , along exceptional wide‐temperature performance (3000 −20 °C 820 °C, ). The Zn||VO 2 full cell retains 87.8% capacity after 2000 cycles 5C, highlighting its high‐rate durability. This multifunctional hydrogel design advances AZIBs toward reliable operation across broad temperature ranges, providing scalable strategy next‐generation systems.
