Rechargeable zinc-air batteries require bifunctional electrocatalysts capable of efficiently catalyzing both the oxygen reduction reaction (ORR) during discharge and the oxygen evolution reaction (OER) during charging. However, their practical application is severely hindered by sluggish ORR and OER kinetics at the air cathode, resulting in reduced energy efficiency and shortened cycle life. Density Functional Theory (DFT) has become an important tool for understanding how these reactions occur and for designing better catalysts to improve performance. This review summarizes recent DFT studies on bifunctional electrocatalysts, including carbon-based materials, single-atom catalysts, transition-metal systems, and transition-metal oxides for ORR/OER applications in rechargeable zinc-air batteries. It discusses transition-metal-based catalysts, which offer strong catalytic activity; carbon-based materials and metal-free nitrogen-doped carbon catalysts, which are lightweight and inexpensive; metal-nitrogen-doped carbon catalysts, which show excellent stability and high activity; and transition-metal oxides, which are abundant and durable alternatives.

Yttria-stabilized zirconia (YSZ) is a well-established material for oxygen-ion conduction; however, the fabrication of thin and dense electrolyte layers generally requires specialized manufacturing processes. Although advanced deposition techniques, such as physical vapor deposition (PVD) and chemical vapor deposition (CVD), can produce high-quality films, they are costly and difficult to scale up. In this study, a more cost-effective route for fabricating YSZ films is proposed, combining tape casting, spin coating, and calendering. YSZ films were deposited onto NiO/YSZ anodes fabricated by tape casting using aqueous slurries. Scanning electron microscopy (SEM) and impedance spectroscopy (IS) were employed to evaluate the film microstructure and ionic conductivity. The resulting films achieved a conductivity of 0.37 S cm–1 at 800 °C, approximately seven times higher than the typical YSZ conductivity of 0.05 S cm–1.<h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":665,"journal":{"name":"Journal of Solid State Electrochemistry","volume":"30 9","pages":"3279 - 3290"},"PeriodicalIF":3.1,"publicationDate":"2026-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10008-026-06651-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148710329","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
