Abstract The structures and properties of the electric double layer (EDL) on zinc (Zn) anodes significantly influence cycling rate performance aqueous Zn batteries (ZBs). Here, a strategy is reported to regulate EDL structure through work function ( W f ) engineering effectively enhance electrochemical ZBs, which enabled by electrolyte‐tailored growth heterogenous metal with large anode. metal‐to‐metal charge transfer in heterostructured induced disparity increases surface density, enriches ions shortens thickness EDL. compressed weakens repulsive force deposits achieve tightly stacked dendrite‐free deposition. Besides, formed H 2 O‐deficient enables inorganic‐rich solid electrolyte interphase (SEI) high Zn‐ion conductivity inhibit notorious parasitic reactions improve electrode reaction kinetics. Consequently, Zn||Zn symmetric cells demonstrate an ultra‐long life over 2700 cycles (the cumulative capacity reaches 5400 mA h cm −2 at current density 50 . show average Coulombic efficiency 99.70% 3650 cycles. Zn||MnO full exhibit excellent practical‐level under cyclic continuous mode (3000‐cycle rates) intermittent (1170‐cycle 83.05% retention). Practical pouch are also demonstrated outstanding performance.

Aqueous zinc ion batteries (AZIBs) have emerged as promising candidates for large-scale energy storage systems during post lithium-ion era, drawing attention their environmental-friendliness, cost-effectiveness, high safety, and minimal manufacturing constraints. However, the long-standing roadblock to commercialization lies in dendrite growth parasitic reactions (hydrogen evolution reaction water-induced corrosion) of metallic anode, which strongly depends on complicated interphasial chemistries. This review, with a focus optimizing anode/electrolyte interphase, begins by elucidating intrinsic factor ions' migration, diffusion, nucleation, electro-crystallization, nucleus AZIBs, along underlying scientific principles. Then electrochemical theories pertinent plating behavior interphase is systematically clarified, thereby enriching understanding how anode structure electrolyte design principles relate electrode interphase. Accordingly, rational strategies emphasizing structural engineering been summarized discussed detail. The mechanisms, advances, drawbacks, future outlook these are analyzed purpose fabricating chemically electrochemically stable Finally, challenging perspectives major directions proposed. review expected shed light developing high-performance Zn anodes use sustainable AZIBs.
