Synergistic Enhancement Effect of Maxwell Polarization and Preferential Exposure of Zn (101) Plane toward Superhydrophobic Separator for Ah-Level Zinc Metal Pouch Batteries.

ABSTRACT: Interfacial instability in aqueous zinc metal batteries (AZMBs) leads to uncontrolled dendrite growth and water-induced parasitic reactions, limiting their practical applications. In this work, a novel superhydrophobic HfO₂-coated functionalized glass fiber separator is proposed. Characterized by its high dielectric constant, HfO₂ can autonomously generate an oriented electric field under external electric field stimulation, ensuring uniform distribution of the electric field and Zn²⁺ flux at the interface. This strategy not only enhances Zn²⁺ transport kinetics but also effectively suppresses the migration of SO₄ ^2- via electrostatic repulsion. Furthermore, the HfO₂@GF separator promotes the deposition of Zn
