摘要

制备了一种新型阳离子水凝胶电解质，以解决平衡水凝胶性质的三方权衡的重大挑战。阳离子表达途径通过动态离子排斥力实现快速和选择性的Zn2+运输，实现高离子电导率（28.7 mS cm−1）和Zn2+转移数（0.79）。水凝胶在- 15至60°C范围内具有出色的循环稳定性，显示出实际柔性电池应用的巨大潜力。

Water-Restrained Hydrogel Electrolytes with Repulsion-Driven Cationic Express Pathways for Durable Zinc-Ion Batteries

Highlights

A novel cationic hydrogel electrolyte is prepared to address a significant challenge of balancing the tripartite trade-offs of hydrogel properties.
Cationic express pathways enable fast and selective Zn²⁺ transport through dynamic ionic repulsion, achieving high ionic conductivity (28.7 mS cm⁻¹) and Zn²⁺ transference number (0.79).
The hydrogel demonstrates exceptional cycling stability across − 15 to 60 °C, showcasing great potential for practical flexible battery applications.

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary, and open-access journal published under the SpringerOpen brand. Nano-Micro Letters focuses on the science, experiments, engineering, technologies, and applications of nano- or microscale structures and systems in various fields such as physics, chemistry, biology, material science, and pharmacy.It also explores the expanding interfaces between these fields. Nano-Micro Letters particularly emphasizes the bottom-up approach in the length scale from nano to micro. This approach is crucial for achieving industrial applications in nanotechnology, as it involves the assembly, modification, and control of nanostructures on a microscale.
