Bolstered Interfacial Field Chemistry for Deep Fast‑Charging Aqueous Zinc Metal Batteries (IMAGE)
Caption
- A sulfosuccinic acid-enabled interfacial field chemistry strategy is developed to regulate the inner Helmholtz plane, which homogenized ion/electric distribution, thus accelerating Zn2+ desolvation and charge transfer under high current density.
- This strategy enables superior reversibility and ultralong stability in Zn||Zn cells, simultaneously meeting the requirements of high current density and deep discharge.
- The optimized Zn (10 µm) ||I2 full cells deliver over 1490 cycles (N/P = 2.31) and 680 cycles in pouch cells (N/P = 2.04), respectively.
