Abstract The low capacity, poor cycling life, and rapid self‐discharge hinder the development of carbonaceous dual‐ion batteries (DIBs). Conventional preparations element doping amorphous carbons are cumbersome, complex, difficult to control element, content, size. Here, a nitrogen‐oxygen co‐doped carbon nanomaterial (NDC) with unique 3D vortex‐layered structure high content is ingeniously prepared via self‐assembly hydrogen‐bonded organic framework precursors followed by one‐step pyrolysis, then used for anodes DIBs. By pairing commercial Nylon separator, self‐supporting independent graphite cathode, high‐concentration electrolyte, NDC‐based DIBs display an ultra‐high specific discharge capacity up 519 mAh g −1 at 1 C, rate 0.85% h , retention 98.8% after 1500 cycles, fast kinetic dynamics. This study offers novel approach enable nanomaterials energy‐dense long‐cycling

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

Flexible rechargeable Zn-air batteries (FZABs) exhibit high energy density, ultra-thin, lightweight, green, and safe features, are considered as one of the ideal power sources for flexible wearable electronics. However, slow overpotential oxygen reaction at air cathode has become key factors restricting development FZABs. The improvement activity stability bifunctional catalysts a top priority. At same time, FZABs should maintain battery performance under different bending twisting conditions, design overall structure is also important. Based on understanding three typical configurations working principles FZABs, this work highlights two common strategies applying to FZABs: 1) powder-based 2) self-supported cathode. It summarizes recent advances in electrocatalysts explores various types catalyst structures well related mechanistic understanding. latest research advances, paper introduces discusses modulation expects guide synthesis preparation efficient catalysts.

Abstract Zinc–air batteries (ZABs) hold significant promise for flexible electronics due to their high energy density and low cost. However, practical application is hindered by the sluggish kinetics of oxygen evolution reduction reactions (OER/ORR). This study highlights a novel design vertical graphene arrays (VGs) anchored on PrBa 0.5 Sr Co 1.8 Ru 0.2 O 5+δ (PBSCRu) perovskite nanofibers, fabricated via plasma‐enhanced chemical vapor deposition. Notably, VG growth induces exsolution nanoparticles from PBSCRu perovskite, resulting in unique PBSCRu‐Co‐VG heterostructure. Theoretical calculations demonstrate that constructing heterojunction regulates interfacial electronic redistribution, thereby lowering barriers both OER ORR. As result, PBSCRu@VG‐5 electrocatalyst exhibits superior stability higher peak power liquid solid‐state ZABs compared pristine electrocatalyst. protocol advances integration synergetic perovskite/metal/graphene composites, offering considerable potential next‐generation conversion technologies.
