For many multivalent systems, such as rechargeable magnesium batteries, which offer great potential for high energy density and utilize earth-abundant resources, electrolyte instability and electrode surface passivation, arising from electrolyte decomposition, remain as major roadblocks. Understanding the electrolyte decomposition pathways at the electrode-electrolyte interface is essential to provide guidance in overcoming this challenge.

Herein, the gating mechanism based on interfacial ion flipping is proposed to stabilize the anode interface, suppress side reactions and facilitate dendrite-free Zn deposition. Under the specific adsorption of anions, water molecules are effectively expelled by hydrophobic cyclohexyl, thereby mitigating corrosion. Moreover, under the influence of electric field, negatively charged anions undergo flipping, enhancing cation transfer. Sodium ions preferentially adsorb at the electrode protrusions, creating an electrostatic shielding effect. Simultaneously, Zn ions redistribute spatially, thereby achieving uniform Zn deposition. Through the synergistic effect of anion flipping, a distinctive gating mechanism is established within the electric double layer, which precisely modulates the distribution and behavior of cations, water molecules, and anions at the interface.
