What is Successive Gradient Internal Electric Field Strategy Toward Dendrite‐Free Zinc Metal Anode about?

With the rapidly increasing demand for grid-scale energy storage systems, rechargeable aqueous zinc ion batteries (ZIBs) are capturing attention as a highly promising technology with low cost and high safety. Nevertheless, rampant dendrite growth, hydrogen evolution reaction (HER), and corrosion of the zinc anode have dramatically impacted their practical application. Here, a self-supported modified layer with ultrafine high-entropy nanoparticles (2 nm) as the zincophilic sites is realized to modify the Zn anode for the first time. High-entropy materials with unique continuously distributed potential gaps significantly reduce the activation energy of multi-electron reactions and modulate ion transport during zinc deposition. Moreover, thanks to the hydrophobic properties and effective desolventizing ability of the ultrafine high-entropy nanomaterial, the unfavorable side reactions of the zinc anode are prevented to promote the zinc deposition process. As a result, stable cycling of 3500 h at 1 mA cm -2 and 600 h at a high current density of 10 mA cm -2 is achieved. Coin cells and flexible pouch cells assembled with KMO and NH 4 V 4 O 10 cathodes also demonstrate promoted electroche
