A multiscale theoretical framework deciphers the molecular-ionic dynamics of the electric double layer (EDL) in aqueous rechargeable zinc batteries, correlating interfacial water aggregation, anion-specific adsorption, and electric field inhomogeneity to parasitic reactions and dendrite growth, thereby establishing EDL-driven design principles for ultra-stable Zn anodes. Molecular adsorption engineering creates a localized “water-poor and anion-expelled” EDL configuration that suppresses hydrogen evolution and by-product formation while enabling dense Zn electrodeposition through flattened interfacial potential gradients and reduced Zn2+ electrostatic repulsion.
