Bioinspired Hierarchical Hydrogel Electrolyte for Ultralong‑Life Flexible Zinc‑Ion Batteries (IMAGE)
Caption
- Drawing inspiration from the “adhesion-conduction” architecture of spider webs, a hierarchical hydrogel electrolyte (MTP) is developed with uniform 3D ion-conductive pathways.
- Specific “sticky sites” on the MXene/tannic acid network facilitate superior electrochemical properties, including a high Zn2+ transference number of 0.833 and ionic conductivity of 27.69 mS cm−1.
- This strategy enables stable Zn anodes with an impressive lifespan of 4600 h (>6 months) and empowers flexible full cells with outstanding cyclability over 10,000 cycles.
