Abstract Organic additives with high‐reduction potentials are generally applied in aqueous electrolytes to stabilize the Zn anode, while compromise safety and environmental compatibility. Highly concentrated water‐in‐salt have been proposed realize high reversibility of plating/stripping; however, their cost viscosity hinder practical applications. Therefore, exploring low‐concentration salts, that can be used directly anodes, is primary importance. Herein, we developed an asymmetric anion group, bi(difluoromethanesulfonyl)(trifluoromethanesulfonyl)imide (DFTFSI ‐ )‐based novel zinc salt, Zn(DFTFSI) 2 , obtain a ionic conductivity highly stable dendrite‐free anode. Experimental tests theoretical calculations verified DFTFSI − 2+ solvation sheath inner Helmholtz plane would preferentially reduced construct layer‐structured SEI films, inhibiting hydrogen evolution side reactions. Consequently, symmetric cell 1M electrolyte delivers ultralong cycle life for >2500 h outperforming many other conventional salt electrolytes. The Br battery also exhibits long lifespan over 1200 cycles at ~99.8 % Coulombic efficiency capacity retention 92.5 %. Furthermore, this outstanding performance translates well high‐areal‐capacity (~5.6 mAh ⋅ cm ‐2 ), cycling 320 95.3 initial retained.

In order to facilitate electrochemical oxygen reactions in electrically rechargeable zinc-air batteries (ZABs), there is a need develop innovative approaches for efficient electrocatalysts. Due their reliability, high energy density, material abundance, and ecofriendliness, ZABs hold promise as next-generation storage conversion devices. However, the large-scale application of currently hindered by slow kinetics reduction reaction (ORR) evolution (OER). development heterostructure-based electrocatalysts has potential surpass limitations imposed intrinsic properties single material. This Account begins with an explanation configurations fundamentals electrochemistry air electrode. Then, we summarize recent progress respect variety heterostructures that exploit bifunctional electrocatalytic overview impact on ZAB performance. The range heterointerfacial engineering strategies improving ORR/OER performance includes tailoring surface chemistry, dimensionality catalysts, interfacial charge transfer, mass transport, morphology. We highlight multicomponent design take these features into account create advanced highly active catalysts. Finally, discuss challenges future perspectives this important topic aim enhance activity batteries.
