Nevertheless, its practical implementation is impeded by severe chloride-induced corrosion and the competing chlorine evolution reaction (CER), both of which predominantly affect the anodic oxygen evolution reaction (OER) and consequently deteriorate the overall efficiency and long-term operational stability of the seawater electrolysis system for sustained hydrogen generation. To address these issues, this study introduces a Ni<sub>3</sub>N selective anion-gating interlayer (SAGI) on a nickel foam substrate. This SAGI increases the electron density at the catalyst surface, effectively repelling Cl<sup>−</sup> ions from the nickel foam skeleton while allowing OH<sup>−</sup> ions to access the NiFeAl-LDH catalytic surface. As a result, the electrolyzer requires only 1.92 and 2.12 V to achieve current densities of 400 and 1000 mA cm<sup>−2</sup>, respectively. Moreover, the electrode demonstrates excellent durability, showing only a 5.8% and 13.6% increase in cell voltage after 500 h of continuous operation at 400 mA cm<sup>−2</sup> in simulated and real alkaline seawater, respectively. This strategy is broadly applicable, extending the operational lifespan of various seawater electrolysis catalysts by 2–10 times, offering a promising approach to developing corrosion-resistant, high-performance electrocatalysts for direct seawater splitting.</p>","PeriodicalId":100685,"journal":{"name":"Interdisciplinary Materials","volume":"5 1","pages":"180-191"},"PeriodicalIF":24.5,"publicationDate":"2026-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/idm2.70031","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146215906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lithium iron phosphate (LiFePO<sub>4</sub>, LFP), with its superior safety, long cycle life, and cost advantages, has become a cornerstone cathode material. However, the limited energy density (ED), attributed to its relatively low nominal voltage (~3.2 V) and moderate specific capacity (~170 mAh g<sup>−1</sup>), hinders its competitiveness in high-energy applications. Furthermore, electrochemical characteristics related to poor charge transfer kinetics and material circularity also limit its overall value. This review highlights recent advances in material design, electrode engineering, and system-level optimization aimed at overcoming these challenges. Key strategies include precision doping, multifunctional coating, and nanostructuring to enhance conductivity and rate performance, development of high-tap-density powders and ultra-thick electrodes for improved ED, and hierarchical electrode architectures and advanced conductive networks for efficient ion/electron transport. Additional focus is given to low-temperature performance, scalable and sustainable synthesis routes, and recycling pathways that ensure long-term environmental viability. Emerging directions such as dry electrode processing, solid-state integration, and artificial intelligence/machine learning-driven optimization are also discussed as transformative tools for accelerating LFP innovation.
