Abstract The stability of the Zn metal anode is significantly affected by various parasitic reactions during plating/stripping. Here, sodium 4‐aminobenzenesulfonate (SABS) a functional electrolyte additive to modulate electrode/electrolyte interface protect metal. An electrical double layer (EDL) reconstruction providing hydrogen bond sites through nitrogen and oxygen elements with lone pair electrons in SABS molecules. These strong bonds not only limit corrosion free H 2 O molecules on surface but also promote desolvation process. Besides, can be further situ decomposed into solid (SEI) regulate plating/stripping behavior 2+ . As result, based synergism organic–inorganic hybrid SEI EDL reconstruction, Zn//Zn symmetric cells exceptionally survive lasting for 6500 hours at 1 mA cm −2 mAh , over 900 cycles even 40 10 Zn‐I full cell maintains excellent cycle 92.4% after 20000 cycles. Remarkably, pouch capacity retention 99.1% (63 mAh) 820 5

The solar-driven photorechargeable zinc-ion batteries have emerged as a promising power solution for smart electronic devices and equipment. However, the subpar cyclic stability of Zn anode remains significant impediment to their practical application. Herein, poly(diethynylbenzene-1,3,5-triimine-2,4,6-trione) (PDPTT) was designed functional polymer coating Zn. Theoretical calculations demonstrate that PDPTT not only significantly homogenizes electric field distribution on surface, but also promotes ion-accessible surface With multiple N C=O groups exhibiting strong adsorption energies, this reduces nucleation overpotential Zn, alters diffusion pathway

Abstract Aqueous batteries employing Zinc metal anodes (ZMAs) are considered to be promising next‐generation energy storage systems. However, the severe interfacial side reactions and dendrite growth restrict practical application of ZMAs in aqueous electrolytes. Herein, a water‐insoluble dual‐ionic electrolyte additive yttrium 2,4,5‐trifluorophenylacetate (YTFPAA) is developed stabilize ZMAs.
