Published: Nov. 14, 2024

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.

Achieving Fast Ionic Transport and High Mechanical Properties of Cellulose-Based Solid-State Electrolyte via a Cationic Chain-Extended Effect for Zinc Metal Batteries

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

Published: Feb. 2, 2025

In recent years, rechargeable aqueous zinc metal batteries have ushered in rapid development, but their large-scale industrial application is hindered by anode dendrite formation and hydrogen evolution reaction. Using a solid-state polymer electrolyte one of the strategies to solve this problem. Herein, introducing chain-expanding effect salts on oxidized bacterial cellulose, cellulose-based electrolytes with excellent strength ionic conductivity are prepared. According thermogravimetric calculations, bound water content prepared greatly increases, which slows down occurrence side reactions. More importantly, expanding distance between fiber chains provides more space for movement Zn2+. The obtained displays high (38.26 mS cm-1) good mechanical properties (tensile stress 592 kPa tensile strain 381%). Due solid itself, its electrochemical window expanded 2.58 V. assembled Zn∥Zn symmetrical battery maintains an ultralong cycle lifespan over 980 h 0.5 mA cm-2. Zn∥NH4V10O10 specific capacity (363.1 mAh g-1 at 0.1 A g-1) shows satisfactory rate performance.
