Abstract Rechargeable Zn‐air batteries offer the advantages of environmental friendliness, safety, low prices and high energy density, are highly valued. However, major challenge faced by rechargeable nowadays is efficiency due to slow reaction kinetics electrocatalyst at air cathode. Bifunctional catalysts key development improving their overall performance long‐term cycling stability. Metal‐organic framework (MOF) materials have shown great benefits as oxygen electrocatalysts in promoting reduction (ORR) evolution (OER). This paper reviews recent advances three kinds MOF bifunctional for batteries. Additionally, this also discusses synthetic design strategy composite derivatives, concludes suggesting application field

Abstract Tailoring the electronic structure of later transition metal‐based electrocatalysts by incorporating early metal based on complementary effect is anticipated to enhance electrocatalytic activity. Herein, modulation Fe 3 C through utilization Mo 2 promote oxygen reduction reaction (ORR) activity reported. In situ characterizations combined with theoretical calculations reveal that electron‐donating capability molybdenum in active center iron optimizes adsorption and activation oxygen. Concurrently, d‐band much closer Fermi level, which reduces energy barrier for rate‐determining step ( * OOH → O), thereby enhancing ORR alkaline media, catalyst delivers a half‐wave potential E 1/2 ) 0.89 V maintains its efficiency mere 8 mV decay after 10 000 cycles, surpassing Pt/C. Moreover, it can serve as an air cathode both liquid‐state all‐solid‐state zinc‐air batteries (ZABs) shows promising applications portable devices. This work brings innovative design concept highly efficient suitable advanced

Abstract A stable stripping/plating process of the zinc anode is extremely critical for practical application aqueous metal batteries. However, obstacles, including parasitic reactions and dendrite growth, notoriously deteriorate stability reversibility anode. Herein, Methyl l‐α‐aspartyl‐l‐phenylalaninate (Aspartame) proposed as an effective additive in ZnSO 4 system to realize high reversibility. Aspartame molecule with rich polar functional groups successfully participates solvation sheath Zn 2+ suppress water‐induced side reactions. The self‐driven adsorption on improves uniform deposition a dose 10 m . These synergetic functions endow significantly long cycling lifespan 4500 h. cell coupled vanadium‐based cathode also exhibited high‐capacity retention 71.8% after 1000 cycles, outperforming additive‐free counterparts.
