Water‑Restrained Hydrogel Electrolytes with Repulsion‑Driven Cationic Express Pathways for Durable Zinc‑Ion Batteries (IMAGE)
Caption
- 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.
