Hydrated Network Interphase with Dynamic Negatively Charged Microregion Enables Ultra‑Stable Aqueous Zinc‑Ion Batteries

Caption

  • A hydrated network interphase with dynamic negatively charged microregions is constructed in situ via electrochemically triggered Zn2+/SO42– synergy, enabling triple synergistic regulation of Zn deposition.
  • The HNI-modified Zn anode achieves ultra-long cycling (8650 h at 1 mA cm–2 and 1600 h at 10 mA cm–2) and high Coulombic efficiency (99.71%).
  • The Zn//I2 cell delivers a high specific capacity of 356.27 mAh g–1 at 1 A g–1 and retains 89.15% capacity after 12,000 cycles.
