However, issues such as restacking, surface oxidation, and limited long-term stability restrict their practical performance. Carbon materials, including graphene, carbon nanotubes, carbon nanofibers, activated carbon, and porous carbons, provide ideal counterparts for MXenes due to their excellent conductivity, structural tunability, and mechanical robustness. The integration of MXenes with carbon not only prevents sheet restacking and enhances ion/electron transport but also improves electrode stability and cycling reversibility. In this review, recent progress in MXene/carbon composites for ZIBs is summarized, focusing on their synthesis strategies, structural engineering, and electrochemical behavior. Particular attention is given to the synergistic storage mechanisms, dimensional matching, and the influence of heteroatom doping or porous architectures on charge storage kinetics. Beyond laboratory-scale studies, the scalability of composite fabrication, electrolyte optimization, and full-cell demonstrations are highlighted as crucial steps toward practical implementation. Finally, existing challenges such as green synthesis routes, interfacial regulation, and long-term cycling stability are discussed, and future perspectives are proposed to guide the rational design of MXene/carbon hybrids as next-generation high-performance ZIB electrodes.FulltextenMXenesBiocharProduction methodsStorage mechanismsEnergy storageArticlen/a
