Although some strategies have been triggered to address the intrinsic drawbacks of zinc (Zn) anodes in aqueous Zn‐ion batteries (ZIBs), the larger issue of Zn anodes unable to cycle at a high current density with large areal capacity is neglected. Herein, the zinc phosphorus solid solution alloy (ZnP) coated on Zn foil (Zn@ZnP) prepared via a high‐efficiency electrodeposition method as a novel strategy is proposed. The phosphorus (P) atoms in the coating layer are beneficial to fast ion transfer and reducing the electrochemical activation energy during Zn stripping/plating processes. Besides, a lower energy barrier of Zn2+ transferring into the coating can be attained due to the additional P. The results show that the as‐prepared Zn@ZnP anode in the symmetric cell can be cycled at a current density of 15 mA cm−2 with an areal capacity of 48 mAh cm−2 (depth of discharge, DOD ≈ 82%) and even at an ultrahigh current density of 20 mA cm−2 and DOD ≈ 51%. Importantly, a discharge capacity of 154.4 mAh g−1 in the Zn/MnO2 full cell can be attained after 1000 cycles at 1 A g−1. The remarkable effect achieved by the developed strategy confirms its prospect in the large‐scale application of ZIBs for high‐power devices.

Herein, visible-light-driven iron-catalyzed nitrene transfer reactions with dioxazolones for intermolecular C(sp 3 )-N, N = S, and N = Pb ond formation are described. These reactions occur with exogenous-ligand-free process and feature satisfactory to excellent yields (up to 99 %), an ample substrate scope (109 examples) under mild reaction conditions.I n contrast to intramolecular CÀHa midations strategies,a n intermolecular regioselective CÀHa midation via visiblelight-induced nitrene transfer reactions is devised. Mechanistic studies indicate that the reaction proceeds via ar adical pathway.C omputational studies show that the decarboxylation of dioxazolone depends on the conversion of ground sextet state dioxazolone-bounding iron species to quartet spin state via visible-light irradiation.Scheme 1.
