However, AZIBs still face critical challenges in practical applications, such as zinc anode dendrite growth, corrosion, and capacity fading of cathode materials, which hinder their commercialization process. MXenes, two-dimensional transition metal carbide/nitride materials, exhibit immense application potential in AZIBs due to their distinct physicochemical properties, including high conductivities, large specific surface areas, and abundant surface chemistry. This paper reviews the latest research progress of MXene-based materials in AZIBs, delving into the applications of MXenes in cathodes (including the use of pure MXene materials as conductive substrates and the construction of MXene-based derivatives such as composites and heterostructures), anodes (such as serving as carriers for zinc deposition, zincophilic substrates, and protective layers at the zinc metal interface), as well as in separators and electrolytes. Additionally, this review analyzes the modification strategies, performance optimization mechanisms, challenges faced, and future development directions of MXene-based materials. By summarizing existing research findings, this paper aims to provide theoretical guidance and practical references for the further application of MXenes in AZIBs.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"69 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2025-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144769649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cation defect engineering applied to the Na0.96CoPO4 matrix can modulate the oxidation state and electronic structure of Co species, thereby improving the intrinsic activity. Subsequently, Ag nanoparticles are deposited onto the surface of Na0.96CoPO4 via a solution infiltration method. The engineering of Ag modification not only promotes charge transfer, but also further modulates the electronic structure of Co. Benefitting from the tailored electronic structure of Co, the improved intrinsic activity together with the strengthened interaction between Na0.96CoPO4 substrate and Ag nanoparticles modifiers, the Ag@Na0.96CoPO4 composite displays an excellent catalytic activity with a low overpotential of 276 mV at the current density of 10 mA cm-2, markedly superior to the commercial IrO2 of 318 mV.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"150 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2025-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144763463","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
