Abstract
Abstract Aqueous zinc‐ion batteries are promising for next‐generation energy storage systems. However, the zinc dendrite growth, corrosion, and hydrogen evolution reaction at the electrochemical interface severely impede their further development. Herein, a Zn 2+ ‐rich and H 2 O‐poor Helmholtz plane is constructed to regulate the electrochemical interface between the zinc anode and the electrolyte. Electrochemical and in situ spectroscopy characterizations reveal that the designed electric double layer with abundant Zn 2+ coordination sites and less H 2 O content can facilitate rapid electron transfer, homogenize Zn 2+ deposition, and alleviate the side reactions induced by active H 2 O. Benefiting from the…
